You did build the project, right?  The helloworldMPI.exe is in the Debug directory?

Here's a MPI Hello World project based on your code.  It runs fine on my machine.  You'll need to change the include and lib paths as we discussed before to match your paths, and copy those bin files over to the Debug directory.

Run it with this to start:  "mpiexec -n 1 helloworldMPI.exe".  Then change the -n 1 to -n x where x is the number of cores you have.  Say yes to allowing mpiexec firewall access if that comes up.

If this bombs out, there's something wrong on your machine.
