R6034 runtime error while calling a VC8 Dll from c#

[crusoein]

I have ported a Vc6 dll to VC 8. Inorder to test the new dll i have made a test application (console )in c# which calls the C++ unmanaged code using marshalling. First when i run the app i was getting a module not found exception. when i ran the dependency walker i found it needed the runtime libraries(msvcp 80 and msvcr80.dll). so i downloaded it to my app directory.. Now when i run it .. i am getting another error which says "R6034 libraries are not loaded correctly".

I have given generate manifest option in my VC++ dll while building.

any help would be appreciated

Thanks

Have you made a test application in C++ in VS2008?

I would do that first to see of it is a C# or a C++ issue.

My guess is that it is an interoperabilit y problem.
