Sage 100c 2021.2 update failing

I'm trying to install the update on top of my 2021.1 installation (test environment). I have restarted and tried running as domain admin, all still fails. There is no error description and I don't see anything in the event viewer. IT seems to be failing on the merge dictionary files task.
