I've spent some time searching here, as well on search engines and think I have exhausted the normal issues.
I have 10.1 Desktop (Editor) installed on a Windows 2008R2 server with recent patches. I also have a clone of this server in VM format (Hyper-V) on test. The differences are total memory (32GB vs 16GB), total cores "hyperthreaded" (24 vs 4), and drivers for real hardware vs virtual hardware.
Before removing ArcMap 9.3.1 and installing 10.1, I tried the same on the VM without issue. I installed 10.1 on the real server without issue, but it will not start ArcMap or ArcCatalog. I do not have the Data Interop extension loaded (possible OpenGL 2.0) issue, but it still fails when loading extensions according to the log.
Installed extensions (defaults - not authorized) are:
Network Analyst
3D Analyst
Spatial Analyst
Geostatistical Analyst
Publisher
Tracking Analyst
Schematics
VBA
Any thoughts while I wait for ESRI to validate my customer number so I can get support?
Thanks,
Bryan
