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.
