I'm running Fiddler on many virtual machines. The first time fiddler
launches, a pop-up displaying "Possible Conflict Detected" about the
Microsoft Firewall Client in Web Browser Automatic Configuration Mode
displays. I have to 'Cancel' out of it to get rid of it. Next, a pop-
up titled "Folder Creation failed" displays, and I have to click "Ok"
to get rid of it. Next, I get a pop-up displaying that a newer version
of fiddler is available and would I like to upgrade. I have to cancel
out of that too.

I know in the options you can uncheck 'Check for updates on startup',
but is there any way to change these settings or supress all dialogs
programmatically? Via some file or registry setting?

We often do clean installs on the VMs which installs all needed
software automatically. We can't have a person actually go in and
modify these settings after each clean install. Please let me know if
there's any way to do this automatically.

Thanks,
Bonnie

Well, what you're looking for is the QuietMode flag, which you can use
by passing the

-quiet

Command line parameter. However, suppressing the warnings isn't a
good idea in general, because they're there for a reason.

1> If you get the ISA Firewall client message, that means that Fiddler
can get randomly detached with no warning. You should change the ISA
configuration.

2> If you get the "New version available" message, you should install
the new version. It typically fixes a lot of bugs.

3> If you get the "Folder creation failed" message, that suggests
you're running Fiddler without sufficient privileges. This can cause
any manner of unexpected failures later.

Can you elaborate on *why* you're running Fiddler on "many virtual
machines"? What are you trying to achieve?

thanks!

Thanks for the quick response! I have a pool of VMs which run
automated tests, and some of the tests use Fiddler. We update the VMs
with new software periodically but don't want the new version popup to
break all tests as soon as a new version comes out.

If I change the ISA Firewall configuration I think that will mess up
the network settings, and also the setting hasn't caused any problems
yet. My personal computer also has these settings and I use fiddler
all the time.

I am a bit concerned about the folder creation message. I'm not sure
why this is happening. It seems to work fine though if I just dismiss
it.

As for the quiet flag - it seems to work only when run more than once.
If I run "Fiddler.exe -quiet" the first time I will still get all the
popups and have to kill them. If I run it again with the quiet flag
then there are no popups. Any idea why it doesn't work the first time
Fiddler is run (from a clean install)?

Thanks!

Bonnie: The functions for the ISA Firewall Check and the new Version
check both exit immediately if the -quiet command line parameter is
present. The code which warns you if folders cannot be created checks
the Quiet flag before showing any dialogs.

Are you by chance using an extremely old version of Fiddler, which
doesn't have the QUIET feature? You can find the version # inside
Help / About.
