How to make the flash executable work after January 12, 2021?

Question

The Flash EOL is January 12, 2021. Does the Flash Player executable actually stop Flash from working or is it something that can be stopped by Group Policy (in the case of a browser) or WSUS Updates in the case of the up-coming update?

And if so - how can you make flash work after January 12, 2021?

Answer 1

Setting your time on 13 Jan will block flash content to be executed on flash Player plugin, showing this icon:

Answer 2

According to the adobe flash administrator guide in page 28 - it may be possible to allow enterprise flash applications to run.

If the browser will not block you (e.g. if you are using chrome 87 and below or firefox 84 and below) - you may just edit the mmc.cfg as so:

EOLUninstallDisable=1
SilentAutoUpdateEnable=0
EnableAllowList=1
AutoUpdateDisable=1
ErrorReportingEnable=1
AllowListUrlPattern=https://YOUR_URL_HERE:8443

The mmc config is found in directory:

• MacOS: /Library/Application Support/Macromedia
• Windows x86: C:\Windows\System32\Macromed\Flash
• Windows x64: C:\Windows\SysWow64\Macromed\Flash
• For chrome:
  • macOS: /Users//Library/Application Support/Google/Chrome//Pepper Data/Shockwave Flash/System
  • for Win: %USERNAME%/AppData/Local/Google/Chrome/User Data//Pepper Data/Shockwave Flash/System
  • for Linux : ~/.config/google-chrome/User Data//Pepper Data/Shockwave Flash/System/
