Fusion 12 Install Hangs on Catalina 10.15.7

[nhbua]

I'm attempting to upgrade to Fusion 12.1 from 11.5.6 on MacOS 10.15.7.  After clicking the VMware Fusion.app, it prompts with the usual "...app downloaded from the Internet, are you sure...", but then no actual installer screen appears.  

I've opened up Sys Prefs and unlocked Security & Privacy, but see no messages or missing settings there.  I've re-downloaded the Fusion DMG, but always get the same results.

Any ideas?

I found the following in the MacOS console:

Couple of ideas:

1) Make sure you're installing as an administrator account

2) Delete Fusion 11 (drag to trash), empty trash, reboot, then try the install.
