Here is the stack trace of the exception that is thrown when I try to profile my application.
It is easily reproducible. The problem occurs when I build my project for x32 and try to profile on a x64 bit platform with ANTS Profiler.
It does not have any problem running this application normally outside the profiler.
Here are the details of various version numbers:
ANTS Performance Profiler 5.2.0.26
MS Visual Studio 2008 Version 9.0.21022.8 RTM
MS .NET Framework Version 3.5 SP1
OS Name Microsoft(R) Windows(R) Server 2003 Standard x64 Edition
OS Version 5.2.3790 Service Pack 2 Build 3790
