Did you write a type_info class?
There already is one. See typeid in http://www.cplusplus.com/doc/tutorial/typecasting/
Try renaming your class...

I think this is a library conflict. You need to change your build settings to use a different runtime library.

Go in Project | Settings, and look around for the "Runtime Library" option. It'll have options like "Debug DLL", "Multithreaded Debug DLL", etc. Try different options until the linker errors go away (probably need to switch to the multithreaded dll options)
