There are potential workarounds in other answers below. For continuous usage in a browser, I'd prefer following Tetsujin's recommendation and try a standalone but supported Flash player, such as Newgrounds'. Note: In my case, the application using Flash works offline and should present minimal security risks.

Note: the linked page mentions mmc.cfg, but my Flash folder had a mms.cfg file instead maybe it was a typo, but in any case I added the EOLUninstallDisable=1 line. I just tested an offline desktop application which had stopped working, and it works again.

properties > security > advanced > delete the "DENY Everyone" permission NOTE: Flash32_32_0_0_453.ocx (and Flash64) will always be write protected (C:\Windows\SysWOW64\Macromed\Flash on 64-bit) I managed to make the "time bomb defuser" work, as indicated here: Disable EOL uninstall warnings:Īdd "EOLUninstallDisable=1" to mmc.cfg in C:\WINDOWS\system32\Macromed\Flash
