Powermill 2020 crashing while calculating toolpaths

[Anonymous]

I've been having a persistent issue with my PowerMill, where it crashed while calculating mostly corner finishing toolpaths.
A 'SERIALNUM' error appears and a feedback to Autodesk is required so be sent.

I had this happening while changing the starting point of a toolpath. 
I suspect it might be calculating links that creates the issue.

What version of 2020 are you running?  I beleive this is a problem that was fixed in the  2020.2.2 update.

It might be something as simple as that. I stopped using PowerMill for a while. I don't have any version update notification, but I'll still download 2.2 version.

Check if there are updates to your graphics driver as well, this can sometimes cause crashes if out of date.
