To try and eliminate any problems, I stopped TVService and checked it wasn't running in TaskScheduler.
However, MP1.2RC install still hung when it got to installing TVService. I had to kill the install and uninstall exes that were running and when I ran the installer again, it no longer had the upgrade option and said MP1.2 was installed. I went to the deploy folder and ran the package-tvengine.exe and that worked fine.
I've attached the logs from both install attempts, although I can't see anything in either that indicates a problem.
