How to Customize Adobe Flash Player

adobe_flash_player_v10_iconLet’s talk customizing Adobe Flash. You can make your customizations to Flash with the mms.cfg file. The mms.cfg file is a text file Flash will use to apply customizations. We’ll look at some possible customizations and how to silently install Flash on your computers.

Recommended Customizations

There are a great many customizations you can make to Adobe Flash, and you can check out the full list in Adobe’s manual here. (Read the Administration chapter starting on page 24.)

Add as many or as few customizations as you would like to your mms.cfg file. Of course, put one customization per line. Here are a couple personally recommended customizations you can make:

Disable Auto Updates

Probably the most common customization sys admins want is to disable auto update. Here we’ve set this equal to 1 which will disable the auto update. Alternatively, a 0 will get you auto updates.

#Disable AutoUpdate
AutoUpdateDisable = 1

Prevent Access to Webcams and Microphones.

Another way to customize Flash would be to prevent access to webcams or microphones.

#Prevent SWF files from accessing Webcams or Microphones
AVHardwareDisable = 1

Silently Installing Flash Player with Customizations

Within the Package Library, the Adobe Flash package has disabled auto updates. You may want to use that package that is already built and ready to be silently deployed to all your target machines if you don’t require further customizations (which means you can skip . You can use that package as one of three free packages in an Enterprise mode trial. (See how to deploy from the Package Library here.)

Try PDQ Deploy

Or if you like the extra work (not judging, but really…) you can wrap up your custom installation in a cmd/batch file.

You’ll need to save your mms.cfg file to one of these locations:

32-bit Windows – %WINDIR%\System32\Macromed\Flash
64-bit Windows – %WINDIR%\SysWow64\Macromed\Flash

Here is an example of what your cmd/batch file might look like:

\\scranton\deploy\Adobe\FlashPlayer\install_flash_player_18_active_x.msi /quiet /norestart IF %ERRORLEVEL% == 0 goto MMS
exit %ERRORLEVEL%
:MMS
IF EXIST %WINDIR%\System32\Macromed\Flash (
    copy /Y \\scranton\deploy\Adobe\FlashPlayer\mms.cfg %WINDIR%\System32\Macromed\Flash
) ELSE (
    mkdir %windir%\System32\Macromed\Flash
    copy /Y \\scranton\deploy\Adobe\FlashPlayer\mms.cfg %WINDIR%\System32\Macromed\Flash
)
exit %ERRORLEVEL%

In PDQ Deploy (you can use the free download to do this), create a new package (see how) and add your batch or cmd file in the Install File field. Save and deploy your newly created package! You’ll go to Deploy Now and from there, be able to select target machines to deploy to.
