Hello! I am currently trying to resolve an issue of ArcMAP (10.7.1) not running properly.
I applied this fix:
Go to C:\program files (x86)\arcgis\desktop10.7\bin\configuration
Rename folder CATID to CATID_old
Restart arcmap…. All should run properly.
Which allowed the program to open, however it will crash when trying to do anything. This has been an open issue since 6/29/2020. Any Suggestions?
