SCCM windows 10 (64-bit) deployment has mystery task status of "Program rejected (wrong platform)" at the very end of task sequence history report. There are no error codes that I can see in the report. It looks like everything installed correctly. I've tried disabling recently added tasks to see if I can find the culprit, but no such luck.
I don't see anything in the smsts.log. But it's very possible I'm not looking for the right thing.
I've double checked the 64-bit specific package installs to make sure the "requirements" are defined properly.
While I'm trying to find whatever it is I've missed, does anyone have any suggestions on how to find the problem task?
