I have a Windows 7 virtual machine (running on a VMware vSphere server) that I have been using with ArcGIS Desktop 10.3.1 for several months. Yesterday I upgraded to ArcGIS Desktop 10.4.1. When I launch ArcMap, the splash screen comes up for nearly a minute then disappears. The application never actually opens. ArcCatalog will open, but when I exit it generates a crash report every single time.
It tried uninstalling all ArcGIS products. I then deleted all of the related folders from C:\Program Files, C:\Program Files x86, C:\ProgramData, and both from C:\Users\xxxx\AppData\Local and C:\Users\xxxx\AppData\Roaming. I rebooted the virtual machine, then reinstalled ArcGIS Desktop. Once again, ArcMap won't load and ArcCatalog crashes on close.
