Visual C++ Testing problem

I have installed VisualAssert and cFix. I have been using Visual Studio C++ and programming in CLI/C++. I have a working Chess Game Program that works perfectly by itself.....and I have been studying testing and have many examples(with tutorials) I have found on the net, that compile and run in Visual Studio.....

But as soon as I try and implement those tests on my chess game......I get this problem....

This is what its telling me

Any ideas what I'm doing wrong? Im working with windows forms and have a heap of cpp source files.

Any help would be appreciated.

Thanks

Try to set CLR switch to /clr (without pure and safe).
