Can you test your ArcMap this way? Go to the C:\Program Files (x86)\ArcGIS\Desktop10.7\bin directory and double click on ArcMap.exe. Does it start? Please advise.
Okay try this - go to your C:\Users\<user profile>\AppData\Roaming and C:\Users\<user profile>\AppData\Local directories and rename the Esri folder to Esri_Old. Then try to start the ArcMap and ArcCatalog applications. What is the result?
Thank you for all your assistance Robert. So I completed this task. It allowed Catalog to open up again, but Map will initialize, load but then doesn't open the program. Within Catalog - when I try to expand certain files it will attempt to load it but on certain folders will crash.
Hmmm...not good. At this point, I'd recommend you uninstall the ArcGIS Desktop application and reinstall it. Hopefully a clean uninstall/reinstall will resolve this issue.
Same Issue. Certain folders crash catalog. ArcMap 10.7.1 will not open, had same issue with 10.6.1. Uninstalled and upgraded to 10.7.1. Before doing do I cleaned up any registry references to ESRI and ArcGIS as well as deleted all leftover directories from previous install. Still the same issue. My main change was I had installed QGIS and another program which both use different versions of python, so not sure if that is the issue.
Did you ever get this resolved. I have a ticket in with ESRI for a solution, but waiting to get on a call with them for help.
ESRI did get a hold of me and told me to do this and it worked. Hope it helps!
1) Open Windows Settings >> click Apps >> click Apps and Features >> Scroll down until you see ArcGIS Desktop 10.7.x >> Click on this and choose 'Uninstall"
2)If the software asks you to make changes click yes
3)IMPORTANT In the Program Maintenance Window choose 'Repair' and click next.
4) In the Ready to Repair the Program Window click 'Install'
5) Let the software install fully
6) When the install is finished Click 'Finish'
I ran into this problem, and reading the posts here triggered my memory of an old solution that worked for me. Navigate to your Normal.mxt at C:\Users\<your login>\AppData\Roaming\ESRI\Desktop10.7\ArcMap\Templates\ and rename it or delete it. Next time you start ArcMap it will make a new Normal.mxt, and in my case started without problem.
The same holds true for ArcCatalog.gx in C:\Users\hunterr\AppData\Roaming\ESRI\Desktop10.7\ArcCatalog.
