Can not run Tutorial Sims in MFIX 20.1.2

[arubio]

I am unable to use any of the pre-installed sims/tutorials. I get the shown error above about half the time the other half MFIX just crashes.

Error b"'sbatch' is not recognized as an internal or external command

I’ve recently installed MFiX, but when trying to run any tutorial I receive the following error: b"‘sbatch’ is not recognized as an internal or external command,\r\noperable program or batch file.\r\n" Any guidance would be much appreciated. Thank you.
