MC v2 claims Windows 10 is minimum. On a whim I installed it on Windows 7 . Rather than overwrite v 1.5, I installed it in a different location and the installer did not complain. Running however produced a fatal error almost immediately. I'd not ask here, but the MC forum has produced no answers to anything I posted there. The only thing I found suggests a printer profile is missing, but no clues as to how to actually create one from scratch.
