SOLIDWORKS CAM post processor for MPCMC

I’m having the same problem with this hanging up and crashing SW when you try and run the post process. Not that clear to me what the MILL.LIB file is supposed to be.

Having the same issue too, no solution yet, I’ve tried installing UPG2 from camworks universal-post-generator page which gives a MILL.LIB, tried setting paths to it with no luck, still crashes solidworks 2021
