Adobe Flash Player Installing via SCCM but some clients get pop up to install Flash Player

I pushed the active X and NPAPI msi of Adobe Flash Player version (released 12/13) via SCCM.  It successfully installed on most of our clients.

I'm now seeing an issue where a few clients are getting a pop up asking if they want to install Flash Player even when SCCM and Programs & Features both show it ( already installed on the client. 

We went from and jumped to Is there a requirement to install a base version of 24 perhaps I'm just trying to determine why some clients see they have and others are acting like they need Flash Player installed.

Thank you.

You need a approach to your root cause analysis. I think your deployment is fine, otherwise all your computer's will have the same problem. 

  • Maybe Flash was running when upgraded.
  • Might need a reboot.
  • Is it the active x or npapi causing the issue?
  • Check event viewer to ensure the install was complete.
Dig around a bit now, but record your findings, you need to narrow it down, stay with one clean machine to make sure it's ok, then work on a machine with a defect.

I deploy mine the same way and never ran into this issue. But I also make sure I disable the Flash auto-updater by copying mms.cfg to C:\Windows\System32\Macromed\Flash\ and C:\Windows\Syswow64\Macromed\Flash\ with every deployment (using the script type and the .EXE installer rather than the buggy .MSI package Adobe provides). The MMS.CFG file contains the following 2 lines:


and the file is saved using UTF-8 encoding (important as it otherwise does not appear to work right). The Flash installer is ran using the "-install -force" parameters to force a silent install and ignore any newer versions detected (long story).

Let me know if you have any questions.

I download the latest version of the flash removal tool with every new release and run the -uninstall activex switch with it. Then i install the msi and then copy the mms file over. 


"%~dp0uninstall_flash_player.exe" -uninstall activex
msiexec /i "%~dp0install_flash_player_24_active_x.msi" /qn
copy /Y "%~dp0mms.cfg" %WINDIR%\SysWOW64\Macromed\Flash
