Flash player download: download manager is blank
On Windows 10, running FireFox 68.8.0esr (32-bit), I am unable to install or run the Adobe Flash Player.
When I manually try to download flashplayer32_xa_install.exe, I checked "unblock" on the general properties tab, but that still does not let the Adobe Download Manager work. I get a blank screen.

The C:\Users\<user>\AppData\Local\Temp\AdobeARM.log shows the below error

Any suggestions on how to get my Adobe Flash running again?
