Installing Open-MPI on Windows 8.1

I'm trying to install Open MPI for Windows 8.1 and when I searched for it I had instructions to install it on Windows XP and 7, but not Windows 8.1.

The question was asked on stackoverflow a year ago: Installing MPI for Windows , but the question was unclear, so there was no answer.

I also installed MS-MPI , but when I want to compile a simple cC ++ file, Visual Studio 2013 doesn't recognize #include < mpi.h >

.

Can anyone help me?
