Microsoft Visual Studio A reference to ‘OutOfProcServer’ could not be added.

Hi there,
After installation of Microsoft visual studio on my PC with Windows XP (32) I got this error message. My friend too, installed this program, but is running without error. I don’t really know what is this error and how can I solve this. Please help me to solve this problem with the program and tell me why I have this error message?
Thanks!

A reference to ‘OutOfProcServer’ could not be added.
The ActiveX type library D:DatenVSone 2007UACSamplesConsumeMyElevatedCOMOutOfProcServerbinD ebugoutofprocserver.tlb was exported from a NET assembly and cannot be added as a reference,
Add a reference to the .NET assembly instead.
OK
