Problem reinstalling Big Fish Game Manager

Find another app that does what BFGM does that is a 64 bit application. That is the only thing you can do other than to restore back to Mojave 10.14.x using Time Machine. However that will require a total erase and install of your system.

From what I can tell, BGFM only supported 10.6 Snow Leopard thru 10.10 Yosemite.

Which means that it most likely worked all the way up to 10.14 Mojave, because Mojave still supported 32-Bit App's.

Sadly Catalina is a pure 64bit OS and no longer supports any of those old 32 bit App's or Games.

Is it a 32 bit app? If so it will not run on Catalina.

Although it's old, its recommended actions remain identical. Refer to the last reply in it.

I can't reinstall the game manager and there is NO help from Big Fish. Does anyone have any tips?
