Topaz applications not installing with installbuilder
I have a new iMac, with Catalina.
Had issues installing 3rd party software, seem fixed after fixed an issue with symbolic link to private/tmp
Now, can't install Topaz Studio, or Gigapixel.
Seems the installer doesn't even start running. As if blocked by my Mac.
Can't see the certificate in Keychain Access; should I?
{I am admin, and opening app from trusted developer, supposedly. Prefs set for this, not just apps from app store.]
Done a few things, like tried safe boot, tried different admin account, reset Home folder permissions.
Don't have antivirus software.
A few emails back and forth with Topaz about this; not closer to a solution.
