Just installed Pex this afternoon on a Win2k8 R2 SP1 VS2010 SP1 install. I can't for the life of me seem to get Pex to run. Regardless of which platform I target my code for, the exploration host fails. Looking in the event viewer, I see this:
Framework Version: v4.0.30319
Description: The process was terminated due to an internal error in the .NET Runtime at IP 000007FEF9915981 (000007FEF9910000) with exit code 80131506.
This is followed by:
Faulting application name: Microsoft.Pex.exe, version: 0.94.51023.0, time stamp: 0x4cc3190e
