MS MPI does not execute MPI program

I have used MS MPI to develop an MPI program. The program is tested and it works fine.

When I try to run the program in cmd using the following command: 

mpiexec -n 4 a.exe

the console hangs and it does not execute the program. If I try to interrupt using Ctrl+C, the message mpiexec aborting job... appears and nothing exits until I manually kill smpd.exe.
I use MS Windows 7 64bit. The same problem appears when using another machine with this OS. However, everything works fine on a MS Windows 10 machine.
I'd appreciate any clue to the problem.

The issue appears to be when mpiexec calls to smpd.exe to run the application. The smpd.exe process starts and gets stuck in a suspended state. You can go into the windows resource monitor and resume the service, and your program will start normally.

The problem is using the latest version of MS MPI runtime which is v9 at the time of writing. I installed the previous version (i.e. v8) and everything worked fine.
