Hi, I need to run some test on Windows, so I have configuration like in subject: Win7 Pro 64bit + gretl 2023b-git 32bit + MS-MPI 10. When calling simple script: <hansl> mpi     eval $mpirank end mpi </hansl> I'm getting error message that "there is no exit from MPI_Abort8@ procedure". In gretl output I have: "C:\Program Files\Microsoft MPI\Bin\mpiexec.exe" /np 4 "C:\Program Files (x86)\gretl\gretlmpi" "C:\Users\Admin2\AppData\Roaming\gretl\gretltmp-mpi.inp": exit code 3221225785 Is this related with the fact that gretl is 32 bit while Windows 64 bit?
