That example is intended to be run using gretlcli-mpi. So you have to do

mpiexec /np <number of processes> gretlcli-mpi <script-name>

See section 4.2 of the "Gretl/MPI Q & A". If you don't want to do that,
wrap the whole script in "mpi ... end mpi <options>".

I still have to try this. Starting "gretlcli-mpi.exe" demanded admin-rights (firewall problem), which I don't have here atm.

It looks as if you have entered the path to mpiexec.exe as your MPI hosts
file (under Preferences/MPI). That's not right, please see section 4.1 of
the notes, "Establishing a hosts file". But if you're running on a single
machine you don't need (or want) a hosts file, just blank that out in the
GUI preferences.

Ok, I left the host-file path blank, and it works now! But, only the admin-rights gretl version correctly recognizes the MPI library. But this may be due to the fact that I store the no-admin version in my personal folder, but not in "C:\Program Files\gretl" directly. The error message just states that the system cannot find the file (in GER: "Das System kann die angegebene Datei nicht finden.")
