Cannot use MPI 2019.0.045 beta

Hi there!

I am unable to use Intel MPI library from Parallel Studio XE beta 2019 in Windows.

I am trying to compile the following code with mpicc:
http://people.sc.fsu.edu/~jburkardt/c_src/hello_mpi/hello_mpi.c

It seems to compile ok.

However, when I run it with mpiexec there is no output.
mpiexec -n 1 hello_mpi.exe

I don't have this problem with Intel MPI 2018.

Thanks for your help,

Hector
