ArcCatalog 10.1 Crashes when opened.

I have recently upgraded to ArcCatalog 10.1 and I have installed the SP1 as well as teh Background Geoprocessing for 64 bit.

If I go to my start menu and try to open ArcCatalog from there it opens for a brief second, then crashes. I can open ArcMap and it opens no problem. I can access ArcCatalog through ArcMap without any issue.

Any have any fixes? I sent the error report in.


I am running Windows 7 64bit with 8GB RAM

I never had any problems with 10.0...
