This problem seems to be a carryover from what I had going on with a Fresh Install of 3.7.1 on a new machine, and noted in this thread Cannot launch the pipeline tool on Windows 10:
That one was causing the same behavior with a WerFault (If you check Windows logs). Any possibility two people are building that code base with one setup badly? Because it seemed like if going to 3.7.1 was an upgrade it worked fine (Maybe did not overwrite Pipeline.exe), but on fresh install it was broken. My guess is forced overwrite of Pipeline.exe in 3.8.0.1018 -> 3.8.0.1074 upgrade, maybe same underlying WerFault?
