Well, I don't think header files are the problem - it's the libraries,
since it's a linker error.  If you have already specified in the
Project Linker settings the correct libraries to link to, you need to
check your library path settings in Visual Studio.

Click on Tools, Options, Projects and Solutions, VC++ Directories,
then Show Directories for Library files, and move the directory that
contains the libs you want to link against up to the top (or at least
above anywhere else older versions of the libraries could reside).

You might also double check the Additional Library Directories setting
in your Project Settings (if you are using it) to make sure it points
to the right path.

Good luck,
