I just upgraded from 10.3.1 to 10.5 yesterday afternoon. Since that time, I have not been able to view any folder connections in standalone ArcCatalog. It crashes every time. I deleted all of the config files where the folder and other connections are stored but when I add a new folder connection, it crashes as soon as I try to view the folder contents. Strangely enough, if I access ArcCatalog through ArcMap, it works just fine. Has anyone else experienced this issue? I use standalone ArcCatalog quite frequently and this is bothersome. Thanks!
Thank you jayanta.poddar for the suggestion. I just tried this but to no avail. I am now running a "Repair" of the installation. If that doesn't resolve the issue, I will moving back to 10.3.1. Appreciated!
I was having the same problem and before trying to run the repair installation I tried doing a 'refresh' on the connecting folder in the catalog tree which seemed to fix it. I can now connect to my folders without crashing.
I realize this is an older thread, but for those in the future who come across it while troubleshooting...
My 10.5 installation was working just fine on a Win 10 machine. This morning I started having the same problem. The only thing that changed was windows updates were run last night. I added a folder connection to a drive (C:\ and H:\) and then when I tried to browse the contents ArcCatalog would crash. I could browse the connections fine in ArcMap though. I deleted/renamed the C:\Users\...\AppData\Roaming\ESRI\Desktop10.5\ArcCatalog folder multiple times and still couldn't browse the directory. I also tried repairing the ArcGIS Desktop installation via windows and I still had the problem.
Next I tried connecting to a subfolder (e.g. H:\Foo), and I could browse the contents. Very odd.
