Adobe Flash Automatic Updater Prompt

We have configured the mms.cfg file to reflect these settings and so far no more popups.

How do you disable the Automatic Prompt to Update Flash through the network for multiple workstations?

Add AutoUpdateDisable=1 to the mms.cfg file saved at the following location:

• 32-bit OS: C:\Windows\System32\Macromed\Flash
• 64-bit OS: C:\Windows\SysWOW64\Macromed\Flash

We have referenced the following article but multiple machines are still being prompted to update: Disable Adobe Flash Updates on 64-bit Windows with Group Policy We've updated the Group Policy for all workstations and they are still being prompted.

It's possible the system was already configured to display the notification update prior to disabling updates.  For Notification Updates, when an update is encountered Flash Player creates the following two registry entries:

• HKEY_CURRENT_USER\Software\Macromedia\FlashPlayerUpdate
• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce > FlashPlayerUpdate

The presence of the RunOnce > FlashPlayerUpdate entry triggers the Notification Update to display upon logging into the system.  If these entries (especially the RunOnce > FlashPlayerUpdate) do not exist the Notification Update prompt does not display.  You can write a script to periodically check if these entries exist on the system and if they do, delete them.

Note that the AutoUpdateDisable setting in the mms.cfg file is reset to the default setting of AutoUpdateDisable=0 when Flash Player is uninstalled.  If your deployment strategy involves uninstalling Flash Player before installing the new version this option will be reset and you'll need to deploy the custom mms.cfg file again disabling Flash Player Update Notification (AutoUpdateDisable=1) after installing the new version of Flash Player.

More information on this can be found in the Flash Player Administrators Guide.
