I would also like to know more about this fix. I had to change the client installation from GUI to service so I can run them without having to log in to a windows account, but since that, I get a WHOLE LOT of these:
Error: 3dsmax startup: Error getting connection from 3dsmax: Monitored managed process “3dsmaxProcess” has exited or been terminated.
So that must be related.
I tried following your workaround @jrosen but I get blocked by not being able to delete the service account userfolder entirely (because of PythonSync.lock)
Anyone from the Deadline Devteam willing to help me out here ? @MikeOwen
