I'm having the exact same problem as outlined in this post:
All the Profiling methods give the same error on my system. The type of project I'm trying to profile is XNA/C#.
The provided solution to that problem is the only solution I can find using Google but it does not apply to me as I do not have Symantec anti-virus. Also, there are no instances of the SysPlant registry key (as mentioned in the above link) on my system. I have tried disabling all anti-malware and anti-virus software on my system but still get the error. Does anyone else have any other suggestions?
