I have been reading posts here for months and have noticed an increasing
number of Vista users that are having problems with .png files and Windows
Media Player.

This is a suggestion to Microsoft to review the UAC for some issues it has
been causing.

A few months ago, my New HP/Compaq with Vista Home Premium lost it's ability
to view .png files in IE. Running IE as Admin or turning off UAC corrects
(masks) this issue, but not many people want to run as Admin or turn off UAC
permanently. I'm an I.T. guy, and I feel that I know how to troubleshoot and
take methodical corrective steps, however, this issue has remained
unresolved. I am seeing more and more people that are having this problem
with no apparent solution.

Now, this week, Windows Media Player is unresponsive without running as
Admin or turning off UAC. Again, I am seeing an increasing number of posts
with this issue.

It should be noted that re-installing/Restoring Vista has corrected this
issue according to some posts. I do not want to take this measure because if
it happened once, it can happen again. The problem itself should be
identified so that it can be corrected.

I understand that 2 issues do not signify a trend, but the issues seem to be
related to the UAC and I'm wondering what other programs or utilities may be
affected in the future. In my case, my needs are simple. I have Vista and
MS Office. There are no worthless programs or utilities installed, so its
not as if I have been "playing" and installed a program that would have an
adverse affect on Vista.

I have submitted a "bug report" by phone as well.

If anyone else is experiencing this issue, please post.

Good Luck!!!

Jim

Hi,

I find myself in exactly the same situation.

A few months ago I bought a Sony Vaio FE41X that came with Vista Home
edition installed. Since buying the machine I've had a host of Vista related
errors and this is one of the more irritating ones.

Please Microsoft fix this rather thane relying on your users to work around
it by having to run their applications as Administrator - surely this
bypasses any security improvements that Vista claims when running as a normal
user.

Thanks,

Paul.

Same problem I think my problem started when I installed Quicktime. I have
tried all suggestions posted in the discussion groups. Turning off UAC or
starting IE as and admin works for me. Help!!!

Same for me as well. First, I had the problem with my user account. I
transferred my data to a new user account and it has been fine. However,
shortly thereafter, the same problem has popped up for my wife's user
account. Any help would be greatly appreciated.

I, too, am having this problem. I have an HP Pavillion Notebook running
Vista Home Premium. It took me forever to figure out what the heck the
problem was. I performed a system restore and WMP now works and Youtube
plays videos, but .png pics still don't show. I refuse to reinstall Vista.
Too much of a hassle for something that can be patched! Help!!

I'm having the same problem as well. It's kind of ironic that the page I
read this post in is probably one of the more extreme examples of what I'm
looking at in my UAC'd Internet Explorer:

Please help--I'm getting too comfortable with FireFox.

I think he's taken the article down Jane. FWIW, I did try it but received
several security errors when running his .reg file. I think that fix was
designed for XP.

It looks like Ramesh's site has been visited by gremlins ;)

That fix *should* have worked as far as I recall. What errors were you
getting?

Hi Jane,

As I remember Vista complained about not being able to write all of the keys
because some were in use. I also tried it in Safe Mode but had the same
result.
I seem to recall there were several other posters on Ramesh's site who had
similar issues--the last I saw there had been no reply from Ramesh.

Hi Toby,
I worked on this issue last month with a user who faced this problem. Process Monitor log did not contain any "Access is denied" errors, yet the REG file could not be merged successfully. I've put that issue on hold, until I get hold of the computer directly to comprehensively test and repro the problem.

Well after much consideration, I decided to turn off UAC today. Immediately
all programs and utilities began working properly (.png support, Media
Player, Quicktime, etc.)

I really do want to take advantage of the extra added security that UAC
offers, but I also need to have a working OS. I will operate this way until
someone (MS) comes up with a solution. I'm not suggesting that others do
this, but this is what I have decided to do.

Good Luck again...

For those new to this thread, please feel free to post your .png and WMP
problems. We still have not had enough responses for Microsoft to look at
this suggestion thread. Also, please vote for this thread so that it moves
up in the rankings.

I still have this issue on my "new" pc - only 2 months old. I have even
tried turning off UAC and that doesn't work. .PNG files work fine in
Firefox, so it's definitely an IE7 issue. I have IE version 7.0.60000.16473
Updated Versions: 0

Any help from Microsoft would be greatly appreciated as I may have to switch
my to a different browser :(

Having this same issue. Started three day's ago and i haven't installed
anything new or made any changes. I can't even use my HP scanning program
because everything is red x's. I have Vista Ultimate and my rig is custom
built by me. Firefox works though but it runs like crap. Maybe this is some
new kind of virus that affects Vista users. If i run IE7 as admin it will
work for some thing's but it still messes up on some sites forcing me to use
Firefox.

Hello all -

I am in the same boat. Same UAC problem - seemingly came out of nowhere.
Running as administrator is sufficient for now but a pain to confirm
launching IE with admin privileges every time.

I've tried all the fixes everyone suggested on this and other threads and no
success.

HELP!!!

I also have problems with png images not displaying as well as having the
"Stack overflow at line: 0" error message when trying to access google maps
(uses png images).

Tried the reg merge but ran into the "not able to complete because of
running processes". Also checked reg and display inline images which is set
to yes.

Turning off UAC did the trick but will not continue in such a mode.

Running IE7 as administrator cleared up both problems, but I do not know
what type of vulnerability I leave myself open to by running IE as admin. Is
there a down side to this ?

In my case this seemed to start about the same time I installed WHS on my
lan and the server connector app requested that I update my desktop user
password to be the same as my server user password. May be just a
coinsidence, updates from MS and other 3rd party apps come in on a daily
basis :((

I started to have the "no .png display" problem out of the blue last week. I
spent hours scouring the web for suggestions.

The general consensus is to disable UAC to get .png's to display in IE7
again. However, this completely disables the new security enhancements that
the new Vista / IE7 combination provide. Therefore, this solution has proven
usefull for only temporary web journeys.

Further there are other applications on my system that use .png's which are
affected as well. The Adobe CS3 help system, for example. So, this is not
"just a browser" issue.

I wonder why MS hasn't addressed the issue. Is it limited to just a few?

Mr CB

I had QT installed, removing it did not solve my png/IE7 problem. The fix
suggested in the Apple thread did not work for me.

I have solved my problem. IE7 needs to read the values of certain registry
keys in order to display png graphic images. Somehow those keys had become
owner-less, and the value in keys without owners cannot be accessed.
Unfortunately, IE7 wasn't setting an error in any of the event view logs, so
there was no way to determine which registry keys it was failing to access.
Some sharp VB-scripter could probably write something which would step
through the registry and set the ownership of just the keys which required
them, but that's not me. I have documented my method for doing a bulk
re-ownership of the registry branches here:

http://groups.google.com/group/microsoft.public.internetexplorer.general/browse_frm/thread/44774e3711ef2bf0/2cddfb30921f4416?tvc=1#2cddfb30921f4416

Result: I now have png images appearing correctly in IE7. Hope this helps
someone else.

Hi LemJ,

I just noticed your 10/31 post. Thanks for the info. I am willing to try
this on Windows Vista (as a test), but my concern is changing the
"owner"/privileges on objects or subcontainers that may not and should not
have administrator privileges. While this worked for you in XP, isn't this a
round-a-bout way of turning off Vista's UAC? My thinking pattern is that
this gives everything administrative privileges, which is what UAC is
designed to determine on it's own. I hope I'm wrong and I very well could
be. I'm sure this is why you strongly advised to backup the registry first.

What are your thoughts on this? Anyone else have any thoughts on this?

By the way, I'm not saying that your fix was wrong...I just want to be sure
I'm not opening up a "hornet's nest" by giving "wildcard" ownership and
privileges to every entry in my registry (Programs included).

Interested to hear your thoughts.

Jim

Hi Ramesh

Quicktime was already loaded on my PC when bought, I updated quicktime then
followed the directions on your supplied apple link. Removed ALL associations
in QT prefs and disabled all QT add-ons in IE, but png's still not displaying
unless running IE as Admin :(( Png files work in all other apps, including
explorer when viewed as icons.

Seems to me this problem/solution is in the registry, but your reg merge
does not complete it's task because of processes still running. This might
also be a problem with a file's user/groups permissions, which I'm not an
expert on in windows OS.

Thanks for your help with this issue.....

Hi JK,

Using the freeware "Process Monitor" utility, you can check if there any ACCESS DENIED errors when loading a .png file, or when merging my REG file.

With the process monitor I see the following entry:

iexplore.exe 3968 RegOpenKey HKCU\Software\Classes\MIME\Database\Content
Type\image/png NAME NOT FOUND Desired Access: Query Value

This occured when I went to the Windows Vista community webpage, running IE
as user (not administrator). Seems to be the same number of entries in the
process manager as there are png files on the webpage.

As a followup to the process monitor post, I reviewed my registry and
noticed the following:

HKey_Users_Root has a path of:

HKUR\MIME\Database\Content Type\image/png

The entry contains values

HKey_Current_User has no similar path but does have the following:

HKCU\Software\Classes\VirtualStore\MACHINE\Software\Classes\MIME\Database\Content Type\image/png

The entry contains "NO" values

So it looks like IE is looking in the wrong path and that the correct path
is still bad because of the "NO" values.

Hi again Everyone,

After looking at some other threads and reading LemJ's posts, I have written
to (Quicktime) to have them look at this thread. Not sure if it is related
to Quicktime, but some have posted that this problem occured after QT
installation. Now that I think back, I installed QT the same week (prior to
this issue).

I still believe that this is an issue with UAC. The question is, what
caused it (Quicktime?, a Windows update?). UAC appears to be functioning
properly with the exception of .png images and Windows Media Player.

I'll post if I hear anything from the folks at Quicktime.

Hi JK,

It appears that the registry permissions for the HKEY_CURRENT_USER hive is messed up, as "ACCESS DENIED" error is seen in many areas in HKCU. Can you create a new user account and _test_ if the .PNG problem exists there also?

Yes the problem went away when I setup another user "FGHJK"
I then went back to original user "CVBNM" and made "FGHJK" administrator and
"CVBNM" standard user. restarted pc and original user "CVBNM" still would not
display png images :((

I've restored "CVBNM" admin rights and "FGHJK" standard user, my "CVBNM"
account also administrates my lan PCs and servers.

BTW - today's (11/13/07) MS updates for Vista and Office Pro 2007 has really
slowed down my IE, like the browser is waiting for every data object to be
screened before loading pages. This page took 2 minutes to load.

I await further instructions . . . .

Well isn't that interesting... (IKidUNot never had Quicktime). I was really
hoping that we at least had a direction to persue (Quicktime), but I guess
thats not possible now.

That leaves us back at the UAC. That also leaves the "fix" in the hands of
Microsoft. I just wish they would read these posts and at least respond
recognizing that this is a known issue. It obviously is known to all of us.
There are literally thousands of posts in hundreds of threads regarding the
.png issue.

Sorry to post such a dramatic non-technical message, but I honestly don't
know what to do now. I really like Vista, but this is a major glitch that
makes it very incomplete.

Hello all,

I have the same problem as JK. When I create a new user, and use it as
"standard user", png are displayed right, but with my admin account, it still
doesn't work.

I tried to fully uninstall iTunes and Quicktime, then re-attributed the
default program for png files to IE7 (iexplore.exe). Result is, when I
double-click on a PNG file, it opens with IE7, then IE7 asks for allowing the
use of ActiveX.

If I refuse, everything stop here.

If I accept, a new ie7 window opens, and the procedure starts from the
begining, with asking for activeX, and so on.

If there is a png file in a web page (not directly the png file), the red x
comes like described by JK and others.

I believe the PNG files are processed like a programm, or like a application
(like .swf files), but not like an image (jpg) anymore.

But I have no idea how to fix this.

Does that help ?

By the way, I have Vista Ultimate in French, on a dual core 6700, 2.6GHrz,
with 3GB Ram.
Please forgive me for my poor english.
Thx
Elguimauk

Is there a way that i could re-install (uninstall-install) IE7 that would
restore the registry to it's original state for ie7. So that the registry
entries for HKCR\MIME\Database\Content Type\image is restored with it's
entries for png values ?

I'm glad there's finally postings out here regarding this problem! I thought
it was caused by some program I downloaded! I've been having this problem
for almost 6 months! Purchased my HP dv9000 with Vista Home Premium mid-Feb
2007. Problem began happening in June. When I first started searching about
this problem, there wasn't alot out there (at least where I was looking) The
admin account works fine, and my husband is also a user on this pc, and his
account works fine also! Firefox also works fine!
Let's hope microsoft gets on board here and helps us out!

I'm having the same problem. Well, not exactly.
I'm using IE 7, and it recently stopped displaying .png files, oh and
Google Maps causes a stack overflow. I'm not sure exactly when it stopped,
because I mainly use Firefox, except when I find a page that doesn't display
exactly right.

The main difference is that this problem is occurring on my XP SP2 machine,
and not my Vista box.

I've cleared my cache, reinstalled IE7, reinstalled Quicktime, and I even
tried installing Silverlight.

waiting for microsoft to patch with WU i suppose, as the current patch is
too demanding for most users to EVEN TRY to fix it, and since it doesn't
work, why bother?

is there not a real fix out there yet? this is really baffling, i find it

Hi Kamal,

This has not been resolved for me either.

No idea why MS is not responding to this thread. This issue seems to have
happened to many Vista users. It could be happening to many more and they
might not even know it...yet.

I've just been running with UAC turned off and everything works fine. I
don't want to run in this mode forever, though.

A couple of days ago, I "googled" "png wmp uac" and got about 60+ websites
pointing to this thread. Seems that a popular issue like this one, would get
some attention from MS. Also, wouldnt you think that some MS employees would
be having this issue on their own computers as well?

It's an interesting question why I at least haven't heard of anyone inside
Microsoft running into this issue. I'd be interested in running into one of
them, since that would presume that a local box was having this problem and
was available for debugging. I'd like that. =\

Just to clarify so we don't start off on the wrong foot:


> No idea why MS is not responding to this thread.

You might want to read the Newsgroup Expectations of Service here:
http://www.microsoft.com/communities/conduct/default.mspx
, specifically "Microsoft does not offer formal support for the communities
you'll find here." I'm here as a friend. =)

What is the sum total of your problems?
* Is PNG broken in IE?
* Is WMP broken?
* Is QuickTime installed?
If you try the registry merge, what keys are blocked?
What software has been installed to your afflicted system? There should be
a common subset of installed software on afflicted systems that should
likely isolate out to what might have triggered this.

I'm mostly interested in people who have a broken WMP, and knowing what's
going on with their systems. A simply registry monitor trace of what
happens when you try (and fail) to launch WMP, for example, would be really
great data.

For what it's worth, I don't know many WMP-centric people who typically
track this Administration newsgroup. I tend to try to contribute as a
friend to the vista.music_pictures_video and windowsmedia.player newsgroups,
but I don't know of anyone WMP-centric who would likely have stumbled across
this. I saw it mentioned in a post in music_pictures_video, for example. =\

Thanks,
-Zach

Hi Zach, Nice to talk to you again.

Thanks for the link to the MS Expectations info. I posted this type of
thread (Suggestion for Microsoft) so that someone on the "inside" might take
an interest...It must have worked, because now we have you!

Also, the reason, I posted in the Administration, Accounts & Passwords
category is because, in my opinion, the UAC may be the root cause. It's just
a guess, but everyone that I have talked to has turned off UAC to temporarily
resolve these issues or have created a new user. In either case, the issues
went away.

As for your questions...

Is PNG broken in IE? - Yes, I cannot view .png images in Internet Explorer
unless I turn off UAC or run IE as Administrator. Also, IE works on my guest
account (even with UAC enabled).

Is WMP broken? - Yes, WMP will not open unless I turn off UAC or run WMP as
Administrator. Also, WMP works on my guest account (even with UAC enabled).

Is Quicktime installed? - Yes. I have since uninstalled it in an attempt to
correct the issue, but it didnt work. I reinstalled it a couple of weeks ago.

What software is installed on the afflicted system? Since this system has
been affliced with both these issues for 10 months and more software has been
installed since the issues developed, I will attempt to list only the
software that was installed prior to noticing the issues.

Quicktime
MS Office 2000 Pro was installed, but I recently upgraded to Office 2007 Pro.
Macromedia (Adobe) Flash Player
Adobe AR Reader 8
Macromedia (Adobe) Shockwave
Java Runtime (Sun) 1.6.0_03
Microsoft Sync Center
AVG Free Edition
Windows Defender

A note of interest. I had an issue with Java and had to re-install another
version. This was shortly after Vista was released and I think Sun had some
issues with the previous version

As far as the registry merge, I assume you are speaking of Ramesh's png
association registry fix. I don't really know what keys it is failing on,
but it does indeed fail.

As far as the process monitor, I will need to download and install one and
then turn UAC back on. I have only turned UAC on a few times since this
problem has occured. The only reason I have turned it on is to see if a
Windows Update may have resolved the issues.

Thanks again Zach for taking the time to help us and for taking an interest
in this thread.

Yeah, I was kind of thinking I'd get more responses from people in this
groups or more data, but -- there wasn't a lot of good data mined there. =\

What's the association for PNG set to currently? Does setting it to Photo
Gallery fix IE?
IE/WMP working seems to confirm that it's an HKCU corruption/issue.

Ideally I'd like to get the IE/PNG issue working so we can focus on WMP.

So far these are suspect:
HKCU\MIME\Database\Content Type\image/x-png
HKCU\MIME\Database\Content Type\image/png


HKCU\Software\Classes\PROTOCOLS\Filter\image/png

for IE's issue. What are the subkeys/values there?

Hey everyone. I was shocked to find that so many other people were having the
same problems as me.

Enviroment
---------
Windows Vista
IE7
2GB of RAM
Intel Core Duo 2.8GHz

My Problems
---------
Can't display PNG images
Can't display WMP videos
Can't display SWF animations

I have no idea what caused this. One day IE7 jsut stopped working correctly.
The*only* major thing I did prior to this was install and then un-install
quicktime (iTunes).

My Solution
---------
I tried dozens of .reg fixes with no luck. I tried clearing cache,
re-installing quicktime, repairing IE7. Well... you get the idea. Somebody
told me to run IE as an Administrator. I was supprised that my functionality
was restored. So I decided to digg deeper. And I ran two Process Monitors
which took a snapshot of my memory both with IE running in normal and
elevated mode. What I found was, when you run IE in elevated mode, it reads
the prefs from HKCR.. NOT HKCU. I then filtered both capture logs to check
for NAME NOT FOUND against anything with "png" in it's path. Sure enough,
everything that refered to "png" within the HKCU was gone. Not locked out
with bad permissions, but completely gone.

So I simple exported all the .png pngfile keys from the ROOT, into the
CURRENT USER. Hey presto, I now have PNG functionality restored in my
un-elevated IE7.

FIX: http://www.wezcrozier.com/png-fix-ie7-vista.zip

* I can't guarantee this will work. Other .reg fixes seem to concentrate in
fixing the png keys at the ROOT level. Which already present for me, because
I could see PNG's when IE ran with elevated permissions.

* Also, the same thing was screwing up my swf and wmv playback!

Let me know if this helps you guys out.

Cheers,

Wez

Please refer to my thread (december 2007) with Ramesh, there is a wealth of
data in it.

Ramesh was stumped in the end and has not replied since.

BTW - this affects everthing that tries to display a png and the fact that
hkcu/mime does not exist in my registry.

Right, my questions are an extension to the data you've previously provided
and weren't specifically asked by Ramesh. If you do have this specific set
of data, I would appreciate those specific factoids. =)

I don't expect you to have any of those HKCU settings. It is my personal
opinion that setting those is an extremely bad practice. I had long ago
thought about setting those on XP in order to provide for per-user
associations for multimedia file types, and realized that those was a
horrible plan, since the system thus deriving from HKCR settings would end
up with a ghoulash of HKCU-application-a settings and HKLM-application-b
settings, which in my personal opinion is not wise nor sustainable.

I would suspect that you *don't* have HKCU settings here. That would then
lead to the next question - what are the subkeys and values for:
HKCR\MIME\Database\Content Type\image/x-png
HKCR\MIME\Database\Content Type\image/png
HKCR\Software\Classes\PROTOCOLS\Filter\image/png
? But, please, all the questions I've asked have answers that are valuable
to me, so I would appreciate your good faith efforts in addressing them. =)

Thanks,
-Zach

Wez:

when you said "...the same thing was screwing up my swf & wmv playback"
does this mean that just fixing the HKCU keys for the PNG funtionality fixed
WMP too?

Just looking for clarification. Thanks for the great detective work. This
is making me (and plenty of others, I'll bet) hopeful!

OK, this is all very good data so far.

Let's turn to the WMP side of this issue:
* What third party software is installed? I'm primarily interested in codec
packs and that sort of thing.
* When you run WMP in Admin mode, what is listed in WMP's
Help:About:Technical Support Information menu tool?

I would *love* to look at a registry trace:
http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx
, filtered for "wmplayer.exe", of your attempt to launch the player. That
should likely point to a smoking gun.

The file might be big - if you ZIP it or upload it to your favorite file
share site (rapidshare, sendit, etc), that would be a helpful way for me to
be able to take a look.

Heck, I'd even love to take a look at an export of your HKEY_CLASSES_ROOT
registry, but that's potentially extreme overkill. Still: if it moves us
forward here, then it's time well-spent. =\

Thanks for your help here. I would love to be able to look at a system that
reproduces this issue. If you know of the steps required to get into this
state or have a box with this problem in the Seattle area, I'd love to know
about it. =\

Thanks again,

Great, I like the settings that you mention below so far.

Thank you thank you thank you so much !

Well thats interesting, but...

I tried Wez's fix, but I had to modify it so that it matched my HKCR items.
Mine were a bit different. Also, Wez, there were a couple of misspellings in
your registry file (IE:
[HHKEY_CURRENT_USER\Software\Classes\.png\PersistentHandler] - Notice the
HHKEY)

Lo and Behold, .png functionality returned with UAC enabled, but Internet
Explorer still did not function normally. On every website, I get the "Done,
but with errors on page" icon in the lower left corner. WMP still did not
open with UAC enabled. It didnt seem any worse though, and I think Wez may
be heading in the right direction.

Also, as an interesting note...In my case, there is no
[HKEY_CURRENT_USER\Software\Classes\MIME\. The MIME is completely missing in
Classes under Current_User. As well, HKCU only had a few entries under
Classes (only about 10 keys).

Overall functionality is poor with UAC enabled, but is perfect with with it
turned off.

I'm scratching my head for now and until someone (someone a lot smarter than
me) determines the fix, I will run with UAC disabled.

Thanks again WEZ for the post.

I too have started haaving problems with IE7 not displaying .png images on
web sites. I am logged in as the administrator and turning off UAC makes no
difference. Still the problem exists. I have asked several times for
Microsoft assistance and never receive a reply. If this isn't corrected soon
I'm moving to Firefox as my default browser.

The lack of png association in IE also causes the "Stack overflow" problem
in google maps, since the maps are composed of png-s.

Interesting, thanks - I'll take a look. Once thing I notice right off the
bat is that you have you a ton of MPEG/DVD filters - MainConcept, Pinnacle,
Roxio, and Sonic. What editing tool(s) are on this system?

Ideally you could try renaming this file set:
===
muveem2vd.ax
muveedsmpeg.ax
MPEG2VidCodec.dll
DCFilters9.dll
RoxioDVDAudio.dll
sonicdsmpeg.ax
sonicm2vd.ax
PcleAudioCodec.ax
pcleMPEGBox.ax
===
temporarily (to filename.bak or whatnot), but that's obviously a lot to ask.

I'll scan through the logs. Nothing is jumping out at me so far.

Thanks very much for this data.

Zach, I'm not sure who you were asking this question to or if it is posed to
everyone, but in my case, I did install QuickTime at one point. I'm not sure
if it was the cause or if it was around the same time I noticed the issue,
but afterwards, one of the first things I did was to re-associate .png's with
Photo Gallery. That did not clear up the issue.

Also, I posted earlier that Wez's registry fix semi-corrected the .png
issue. Actually, I did not use his registry file. I looked at the keys in
his file and found them in my Root and copied them to my HKCU. It worked,
but not very well. I could see .png's in IE, but I was still getting a
"Done, but with errors on page" on every website. Also, it had no effect on
the wmp issue, obviously. His idea, though may be heading in the right
direction because I noticed that I had no MIME key under Classes on HKCU. I
thought that was a bit strange.

Right now, I am running with UAC disabled. Everything is perfect. It's
only when I run with UAC enabled that these issues re-appear.

Thanks again Zach,

Jim

Right, you should not have needed to copy those keys to HKCU. The fact that
you could not write them is probably the actual problem. That implies that
the privileges/permissions on the HKCR keys were actually what you want to
fix. Those should be broken on those keys, and should be different than
other nearby keys. You should be able to verify those fairly easily in
regedit through checking permissions. =\

Thanks Zach,

I just checked permissions on those keys in HKCR and they are all exactly
the same as the adjacent image keys (.jpg, .bmp, .gif, etc). It is actually
more severe than I thought. Enabling UAC creates many other issues. Flash
Player will not run or install, Library registration errors on all pages
(including the simple google.com), a startup program is blocked and even
though I select "permit" in Win Defender, it does not permit it to run, I
can't even see anything on windowsvista.com with UAC enabled. Then there's
the WMP issue with UAC enabled.

Very frustrating.

If you google ".png uac" or "wmp uac" there are literally hundreds of sites
pointing back to this thread with comments of their own on those support
sites as well.

I'm afraid that this issue needs greater attention than just me trying to
get .png images to display in Internet Explorer. I believe this needs to be
a priority at MS, because this is not just a few users experiencing these
types of UAC issues.

So you don't think I'm soured on Vista...I like Windows Vista. It's
extremely stable, intuitive, and it looks great....but the UAC has some
flaws. The sooner that MS puts a team on this, the sooner it will be
resolved and we can all get back to work. For now, I'll run with UAC
disabled.

By the way, this frustration is not directed at you. You have been great
trying to help us all out and I appreciate your support.

Investigation of this issue will likely be stymied until a way to reproduce
this system on an arbitrary PC can be found. For example, it is now
possible to reproduce the "PNGs will not display in IE" issue given an
install of QuickTime. And thus the right people go off and talk to Apple
about that.

But: how do I reproduce *your* problem? What is the commonality between
your system and these other people? Getting that data turns this from
"random system corruption" into something solvable. We both want that.

Did you use some registry cleaner? What anti-spyware/anti-virus tools are
on the system? It sounds like some bad software accidentally locked down
HKEY_CLASSES_ROOT too far. If you were using a tool to run a registry
monitor during the Flash Player install, that should likely show a variety
of Access Denied error messages during that install pass, I would think.

So right now I'm probably most interested in knowing what was run /
installed to the system when this started happening. Or the total set of
installed software on the system: given N systems with the same problem,
those N systems should have one or two key common aspects, and it's getting
that data set that will allow investigation to really get some place.

I love solving issues, but I've also come to realize that solving them over
the Internet can be very very challenging. For example, in the first
"Windows Media Player won't run on Vista" issue I'm aware of, it was only a
stroke of luck that I managed to get a system to debug and realized that a
bad third party was installing their own private copy of wmp.dll and thus
breaking everything badly. I don't think that's *your* issue though (unless
by chance you had installed SatelliteTVforPC 2006, which was pulled from the
market due to this issue), but -- the more data to work with here, the more
likely it is that a solution can be found.

So: what's the installed set of software on your system? =\

Yeah...your right, Zach, Sorry about the dramatics on the last post, but I
was a bit frustrated. I guess we have to find something common that we have
all installed. I'll try my best to list my programs and I urge others to
compare my list to theirs and please POST!

-This is a Compaq V6210US Notebook.
-OS=WVHP
-Originally came with Norton Security Center, but was uninstalled.
-Now have AVG Free Edition
-Windows Defender
-Office 2007 Pro (Previously had Off 2000 Pro)
-Windows Sidebar is running with Accuweather.com gadget and 2 other gadgets
that were an original part of Vista (Notes and Slide-show)
-Java (Latest Version)
-Macr Flash Player
-Macr Shockwave
-Bejeweled 2 Deluxe
-Microsoft Location Finder
-Live.com 3D maps
-Microsoft Sync Center (PDA Sync)
-Windows Mobile Device Center
-QuickTime
-Bullzip PDF printer (this uses something called ghostscript as well)
-Motorola Q Driver
-VZ Access Manager (Verizon Wireless)


The above programs were installed by me. I won't list the ones that came
packaged with the Compaq, because these issues did not appear out of the box.

Also, I should mention that I installed a program called BitPim, which was a
sync program that was supposed to make it easier to move my contacts back and
forth between my Phone. Didnt work, I uninstalled it and moved to Microsoft
Sync Center.

Thats really it. I'm not one for installing software everytime I hear about
a new gadget (of course, with the exception of Bejeweled 2). Thats really
the only "game" oriented software that is on here. Wouldnt it be something
if that was the culprit?

You mentioned in an earlier post what codecs I have installed. I am using
WMP in it's original form (I think) with no special codecs installed.

Thanks again,

Jim

While I'm putting together the list of stuff installed on that PC, let me say
again that in my case the WMP problem started from one day to the next, with
no changes made to the system (nothing had been installed for at least two
weeks - and no windows updates, either). In fact, the way I found out that
we had a problem wasn't with WMP, it was with Windows Movie Maker (WMM). At
the time we were using it daily tweaking a slide show we were working on, and
it just stopped working, so I thought there was a problem with the .wmv file
and tried to check by using WMP.

And Jim: I've never installed Quicktime or Bejeweled on this PC, so there
goes a couple of possible commons.
Since then, WMM has started working again but I don't know when that
happened, because I hadn't tried using it probably from October until about 2
weeks before Christmas, when I had to finish that slide show.
Does your WMM work?

Keep thinking...

Zach:

On an "undisturbed" installation of Vista (I'm using Premium), can you tell
us the file version info. for WMP.dll? I don't know if we'd all be so lucky
that this would be the culprit on all of our systems, but thought it was
worth a shot.
I presume that there are no apps out there that would normally
disturb/replace/etc this file (other than the ones you've mentioned). Was
that a case where the app had included a file that was inadvertently named
wmp.dll, or did they think they needed to update wmp.dll, and replaced it to
do so, thus messing things up?

Thanks, that's helpful. Did you have or uninstall Norton on this system?
That's been found on two systems so far.

It doesn't appear to be codec related so far, knock on wood.

The default Vista wmp.dll is 11.0.6000.6324. It would be difficult for an
application to *replace* that directly. What one very bad app did was to
install a private copy of wmp.dll elsewhere on the system. This shouldn't
be the case for you - if you *did* have this problem, WMP would actually
crash instead of not launching. You could check for this condition by
searching for wmp.dll on your system.

More questions:
===
What is set for:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\MIME\Database\Content Type\image/x-png
CLSID =
Image Filter CLSID =

HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\MIMEAssociations\image/x-png
UserChoice =

And for those CLSID's - which binary is associated with it?

HKEY_CLASSES_ROOT\CLSID\{nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn}\InprocServer32
= ?

Thanks, that feedback about Norton may be interesting - that's the second
time that's been mentioned. It looks like the codecs aren't the source of
this so far, which is nice.

Would you mind retrying ProcMon but this time filtering down to wmp.dll and
mfplat.dll? Everything in wmplayer.exe seemed to look right.

Also, I'm potentially interested in coming by with a USB memory stick to
get:
* your HKEY_CLASSES_ROOT registry
* your HKEY_CURRENT_USER\Software registry
* a full (unfiltered) ProcMon log of WMP failing (UAC on) and succeeding
(UAC off)

The last by itself will be massive data but likely should point to the
culprit, knock on wood.

It's also probably possible to ZIP or RAR those files up into more easily
transferable packages if you want to go that route, but I don't want to
impose. I greatly appreciate the help and data you've been providing.

(The above requests for information are applicable to anyone hitting this
issue, so do feel free to share if you have that data: I *am* very
interested here.)

Thanks,

So looking at Jim's process monitor logs, we may have found the smoking gun-
what are the permissions for:
HKEY_CLASSES_ROOT\
Typelib\{6BF52A50-394A-11D3-B153-00C04F79FAA6}\1.0\0\win32
on your system?

On Jim's system, this was inaccessible (access denied) with UAC on. Since
that key missing will indeed break the player, this may be the failure point
on your system. Now, if this *is* what is broken, that only potentially
fixes you up and doesn't necessarily figure out the source, but it would be
a nice step forward if I'm correct in my educated guess here.

Thanks for any information here.

WEZ:

Thank-You for the insight to the problem I had with png images not
displaying in IE7. This problem was also causing the stack-overflow problem
in google maps.

I too adjusted your entries for HKCU to mirror my HKCR\MIME registry items.
Similar to what JSandPC did.

Interestingly all the HKCR\MIME entries were mirrored in
HKCU\Software\Classes\VirtualStore but none of the entries had values set :[

If you would like to compare my registry items above to yours they are
located at:

http://www.yourartisans.com/png/HKCR-MIME.reg
http://www.yourartisans.com/png/HKCU-Software-Classes-VirtualStore.reg

Not sure what place the virtual store plays in the system.

My updated version of your registry is located at:

http://www.yourartisans.com/png/My-png-fix-ie7-vista.reg

THANK-YOU Wez !! -- THANK-YOU Wez !! -- THANK-YOU Wez !!

I'm sure this is only a bandaid for just png images, since all of the
HKCR\MIME entries are not populated/mirrored in HKCU. But HAY! png's display,
even in my outlook junk mail ;))

Hm, OK - that seems like a hack designed to work around something denying
read permissions to the HKEY_CLASSES_ROOT hive. I'm very displeased that
something is causing this state and would love to know what is causing this
condition.

If you set the following registry keys:
======
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Classes\Typelib\{6BF52A50-394A-11D3-B153-00C04F79FAA6}\1.0]
@="Windows Media Player"

[HKEY_CURRENT_USER\Software\Classes\Typelib\{6BF52A50-394A-11D3-B153-00C04F79FAA6}\1.0\0\win32]
@=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,\
00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,77,00,6d,00,\
70,00,2e,00,64,00,6c,00,6c,00,00,00

[HKEY_CURRENT_USER\Software\Classes\Typelib\{6BF52A50-394A-11D3-B153-00C04F79FAA6}\1.0\FLAGS]
@="0"
===
, can you then access Windows Media Player normally?

Given the data on the PNG issue, this would potentially tie together:
something is causing HKCR reads to fail for the UAC'd user, and the current
newsgroup solutions are to simply hack around this failure.

My registry suggestion above is rather a hack - it's just to determine if
I'm correct in my diagnosis so far. But if I'm right, it should actually
work. I do not recommend anyone set this on a machine that does *not* have
this problem, as setting HKCU\Software\Classes setting is generally a very
very bad idea, and this is no exception.

OK, we have initial verification now on Jim's machine that this hack does
actually fix the "Windows Media Player not working under UAC" issue. Can
anyone else confirm?

Thus we now get into: who or what is locking down access to:
HKEY_CLASSES_ROOT\ Typelib\{6BF52A50-394A-11D3-B153-00C04F79FAA6}
? I'm assuming there is some common set of bad or removed software on
machines with this problem. As far as I'm aware, the permissions on this
key and subkeys are correct(?).

I would be very interested in knowing the installed and uninstalled set of
software of machines that encounter this problem to understand what might be
the actual culprit here.

My laptop, HP dv9000 with Vista Home Premium purchased mid-Feb
2007, came loaded with Norton Internet Security. My husband removed it with
the Norton Removal Tool, and some other 'helpers' which he cannot remember at
this time. As you probably know, Norton is terrible to try and get out of
your system. Once it was removed, we installed Trend Micro. My problems
with .png images not displaying probably started happening a month or so
after Norton was removed. I don't remember the exact time frame.

Sorry I don't interact much with your discussions - I am much more of a
novice than proficient when it comes to discussing the 'guts' of the pc. But
I have been reading every post and am hoping for a positive resolution to
this problem soon. I have been using Firefox, but I would reallly rather go
back to IE7 if this ever gets resolved. One thing I do find interesting is
that my husband's user account on my laptop does not have any problems
whatsoever.....

Norten came pre-installed for trial period, then I removed it (add/remove)
when it started asking for money. It was constantly getting in my way. Is
there a special tool ? If so then the add/remove avenue should have alerted
user of the need for the special tools, right ? Otherwise pooh pooh on
symantec.

I do not have a problem with wmp, so I did not attemp the reg entries. I'm
confident enough to make IE7 my default browser again. But I'm concerned that
the registry Hack I modified from Wez is just a band-aid to what was
corrupted by an as yet identified application overwriting the registry during
add/remove/update of an application.

Jim:

1) I'm not much of the type to use HP Total Care Advisor types of things, so
I couldn't tell you if it stopped working or not. From the few times that
I've run it, I can tell you that I didn't see anything that looked out of the
ordinary.

2) Since you've got an HP, I'll assume that mine also came with Norton
installed, but to be honest, I just can't remember. I'll have to go back and
look at the list of stuff that's in the software directory when I'm in front
of that computer.
I can tell you that I would have un-installed that software pretty much
right after turning on the computer out of the box (don't care for it, in
case you can't tell). Since I'm unaware of a tool from Symantec to perform
the removal (til now), I would have used the Windows normal method (the
artist formerly known as "Add/Remove Programs").
Can you tell us more about Symantec's removal tool, namely:
What's the difference between removing with this tool vs uninstalling the
"normal" way?
Would it be beneficial to run the tool "a long time" after having removed
the NIS suite?

(slightly ot: I assume your system also came with Roxio CD/DVD Basic v9.
Did this ever work on your computer? I'd like to figure out why this won't
work on mine.)

Steve,

Thanks for the follow-up info. I dont think using the Norton Uninstall tool
would have any benefit at this point. I only asked that question, because I
used the tool and was having the .png/wmp issue. Others have indicated that
they uninstalled using either/or/both methods (Add/Remove and/or Tool), so I
dont think one has any advantage over the other. Furthermore, we're not even
sure what program caused this issue. I was just grasping at straws to see
what may have caused the issue.

As far as Roxio, mine opens up fine and it appears I can access all the
utilities. I did not attempt to burn a cd/dvd, but I opened and played
around with the "Creator Basic", "Express Labeler", and "MyDVD Basic V9".
They all opened. Is your problem with opening the applications? If not, let
me know what your issue was and I will try to duplicate it on mine.

This HP/Compaq and Vista has been virtually flawless, with the exception of
the .png/wmp issue. Now that Zach is involved, that does not seem to be much
of an issue anymore. We "band-aided" the problem by copying certain Root
keys to the HKCU. It's not a permanent fix, but now I have .png's in IE and
WMP opens without a hitch. Well...I guess it is a permanent fix for me,
because the fact that our fix was a "band-aid" is transparent to me. I have
been running with UAC enabled for about 3 weeks now and no worries.

Sorry to keep you waiting so long. Between the two threads and my being slow
to respond, it's getting tough to keep track of questions and answers. I'll
answer each message. Hope it all stays clear.

Yes Norton was installed on the system by the mfg-er. I uninstalled it
very soon after first turning on the system out of the box, as I said I would
have. The interesting thing is that my WMP problems didn't start until well
after I removed Norton, but I'll leave it at that for now.

My wmp.dll is version 11.0.6000.6336
Searching for these DLLs, there doesn't seem to be anything to raise any
eyebrows in the search results.

There's no \MIME\etc. subs below "HKEY_LOCAL_MACHINE\SOFTWARE\Classes\"

There's no \image/x-png below

I thought I ran across a new post from someone who described a WMP problem
that could have been another. I referred her to this thread to check if her
symptoms were simiar. Unfortunately, I haven't been able to find that post
again, nor have I heard anything more. I'll keep an eye out and refer ones
that I see.

Gotcha. Zach's Typelib registry "patch" worked like a charm on my system
too. I'm happy that WMP is working normally again.

Now I just need to find & try the PNG fixes, because I'm guessing that my
registry enties there are compromised too. Somehow I missed those too.

I almost want to start another thread on this, instead of diluting this one.
I tried this tonight too. The Labeler app and MyDYD v9 start fine. The
Creator Basic app doesn't start. When I click on this in the Start menu,
Windows asks me for permission (doesn't do so for the other two apps - hmm!),
then I get the message that

"Roxio Creator has stopped working" and I get the two choices:
"check online for a solution " and "close the program."
(As usual, there's no solution online.)
The "problem details" shows:

Problem Event Name: APPCRASH

I've tried uninstalling the package and re-installing a couple of times.
Although I like the Roxio software for the most part, I just didn't want to
continue pounding my head against this particular brick wall right now. That
may sound like a cop out, but there's only so much time left every day.
<sigh>
I'm glad to hear that you like your computer. I agree that for the most
part it's a nice computer; we like ours too, overall.
