Flash Player Activex Control
Miriam
I'm having lots of problems with the new Adobe Flash 11 player. In the course of trying to diagnose the problem, I found that there is a copy of Adobe Flash 10 player Activex control in my Programs and Features under Control Panels.
The biggest symptom of this condition appears to be extremely slow operation in Firefox with Flash installed...pages take MINUTES to become available. In IE, the browser reported that Flash was not installed, even though it was. In Safari, sometimes Flash would work, sometimes it wouldn't
I also previously had the latest version of Chrome installed, but Flash wouldn't work there either. My undersanding is that Chrome comes with Flash, so I didn't understand how Chrome could not be working with Flash. I uninstalled Chrome a one point trying to see if anything would improve, and I have not yet re-installed it.
I installed the active X plugin for IE but still doesn't work. I know that my applications needs a active X but I don't know the right version to download. I have check adobe site and it gives me a huge list.
By the way I managed to run my software in windows 8 since Win8 has embedded adobe flash player and it works. On the other hand, I installed Adobe Flash player 19 NPAPI and Adobe Flash Player 20 ActiveX on windows 7 but still my software cant run any youtube videos still. Do you have an idea?
I am working on a windows application that has a shockwave flash player embedded in it.The C++ part should be able to call Flash movie methods and vice versa.Initial experiment was done using MFC.It works.But now I want to port it to Qt as it allows easier UI development.Qt has got QAxObject which holds the ActiveX control you assign to it via setCotrol() method which should get a classID of the ActiveX or its name.Because the classID is more reliable than a name and because I have not found an example where flash player ActiveX is accessed using a name ,now I want to know how to retrieve that classID from the system registry of the OS.I suppose that for every machine some specific activeX classID may vary (correct me if I am wrong on it) .If it is true then I need to access the registry ,find shockwave activeX classid and then pass it into QaxObject::setControl() method.How do I do that?
Forgot to mention that in MFC application the ActiveX control gets the requested ActiveX automatically once you select the ActiveX type from the list of available system controls.In Qt you have no such an option.
Reading this I understand that the CLASSID is constant on any machine.Is it true ? If yes then please discard my question as there is no reason searching for the ActiveX key on specific machine by the ProgID if it is the same always.Thanks.
In case of Win 7, Adobe Flash Player is just an application you can install and uninstall.
Starting from Win 8, Adobe Flash player ActiveX is considered to be a part of Windows and it does not appear in control panel and this means there are no entry for Flash under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall key.
Since it is a part of Windows, when you apply monthly update, it takes care flash ActiveX.
While Flash ActiveX is a part of Windows 10, Flash plugins are not.
The HKLM\Software\Macromedia\FlashPlayerPlugin key exists only when you install flash plugin. And version of flash plugin can be different from flash ActiveX.
The Macromedia Flash ActiveX control that is provided with Windows XP contains a memory corruption vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Microsoft Windows XP provides the Macromedia Flash ActiveX control. Depending on the patch level of the system, it may be provided by either flash.ocx or flash6.ocx. This ActiveX control contains a use-after-free vulnerability, which can result in heap memory corruption. Note that this vulnerability does not affect systems that have Flash 9 or later installed, as newer versions of the Flash installer will replace the Macromedia Flash control that is provided by Windows.
Mozilla applications are regularly updated for security and stability; however, Mozilla does not provide updates for plug-ins. Plug-ins can cause crashes and hangs and may contain security vulnerabilities. Visit Adobe's website for information on security and stability issues affecting Adobe Flash.
Adobe Flash (formerly Macromedia Flash), refers to the Flash Player and browser plugin needed to handle SWF videos, web page animations and interactive content. Even though the Flash plugin is also referred to as "Shockwave Flash", it should not be confused with the Shockwave plugin that handles "Shockwave for Director" content.
Note: On Windows, the Flash plugin is detected via plugin scanning. If you have installed the Flash plugin but it does not appear in the Add-ons Manager, open about:config and make sure that the preference plugin.scan.plid.all has not been set to "false" (if it has, right-click on it and select Reset to set it back to "true"). [2]
Note: If the Flash plugin is installed, make sure it is enabled in the Firefox (3.0 and above) or SeaMonkey 2 Add-ons Manager (see above); otherwise, the Flash test will not work and the "Shockwave Flash" plugin entry will not be displayed in the about:plugins list.
If Flash is not installed, this may trigger the Plug-in Finder Service, which you can use to download and install the Flash plugin on Windows (see below). At time of writing, the Plug-in Finder Service is triggered but fails to install the Flash plugin on Linux or Mac OS in Firefox 3 and above (you will need to manually download and install the plugin). [3] [4]
You can also see what version (if any) of the Flash plugin is being detected using about:plugins (see the linked article for details). If Flash is installed and enabled, the about:plugins list will include an entry similar to the following:
Note: The about:plugins list is generated from data stored in the "pluginreg.dat" file. In some cases, the stored data may be incorrect. [5] To refresh the list, close the browser and delete the "pluginreg.dat" file, located in the profile folder in current Mozilla browsers.
To install Flash or to update to the latest version for your operating system, visit the Adobe Flash Player Download Center (see the system requirements and FAQ pages for more information). Adobe has recently started to bundle other applications from other vendors with the download so make sure to opt out of any programs or tools you don't want before clicking the button. Note that recent installers are only helper applications that download the actual application from the Adobe site, thus they are smaller in size than previous downloads.
You can download the full installer for your operating system, without any bundled software, from the Adobe Flash Player Distribution page. Note that, for Mac OS, Flash 10.2 and above is Intel-only. Flash 10.1 r102 is the last supported version for PPC Mac. [6] Archived Flash versions can be downloaded here.
After downloading the Flash installer, completely close your Mozilla application and run the installer. In current versions, the INSTALL button is disabled until you check-mark the box in the Adobe Flash Player installation dialog where it says, "I have read and agree to the terms of the license agreement". See this blogspot article for details, including a screenshot.
Starting with Flash Player 11.2 on Windows, an option for silent, automatic updates is selected by default when you install Flash. This feature will download and install Flash Player updates in the background, without any user interaction. See this Adobe article for more information. [7]
If the Flash plugin is not installed and you visit a page that has Flash content that requires the plugin, the Plug-in Finder Service (PFS) can download and install Flash for you (see this article for details) but it may offer an outdated version. Note: Mozilla may either remove the PFS or change the process for downloading missing plugins, at some future date. [8] [9] [10]
Once the download completes, exit Firefox and run the installer. You normally don't need to uninstall Flash before updating to the latest version, since the Flash installer automatically removes the older version. However, you will need to uninstall your current Flash version if you are downgrading from a higher version.
Important: There are two Flash players offered for Windows users: the Flash ActiveX control for Internet Explorer/AOL and the Flash plugin for Firefox/Mozilla/Opera browsers. Each must be installed separately, since the Flash plugin installer does not add the ActiveX control and vice versa.
You would then have needed to copy these two files to the plugins folder of undetected browsers (e.g., zip builds). Note that an XPI package that was available for Flash 9.0.r28 and earlier using the "Install" link at PluginDoc also copied the Flash plugin files to the Windows System directory's Macromed\Flash folder and added a registry entry so that all Mozilla browsers could find the files through plugin scanning, using a Windows registry PLID scan [11]
Starting with Flash 9.0.r45 the Flash plugin installer for Firefox and other Mozilla-based browsers does not copy any files to the browser plugins folder. Instead, the files "NPSWF32.dll", "flashplayer.xpt" and related files are placed in the Macromed\Flash folder located in the Windows System directory (e.g., C:\WINDOWS\SYSTEM32\Macromed\Flash) and the installer removes any copies found in the installation directory of detected browsers. A Windows registry entry is created enabling each Mozilla browser to detect Flash via plugin scanning (PLID scan). [12]
An uninstaller can be downloaded from Adobe.com to remove Flash from Mac or Windows systems. After downloading, make sure you completely exit your Mozilla browser and close all other Internet applications before you run the uninstaller.
