Open the command prompt by entering “cmd” in the Windows search and clicking on the corresponding icon.
Enter the following command at the command prompt:
where mpiexec
If only the following path is displayed:
C:\Program Files (x86)\Common Files\Intel\Shared Libraries\redist\intel64_win\mpirt\mpiexec.exe
then Microsoft MPI is not installed or not set up correctly.
Download the installation file via the following link: https://download.ktp-software.de/mpi_redist.exe
Execute the downloaded file and follow the installation wizard. Use the default settings.
The computer must be restarted after installation.
After the restart, open the command prompt again. Enter the command again:
where mpiexec
If the installation was successful, two paths should be displayed:
C:\Program Files\Microsoft MPI\Bin\mpiexec.exe
C:\Program Files (x86)\Common Files\Intel\Shared Libraries\redist\intel64_win\mpirt\mpiexec.exe
This completes the installation.
