I've tried to upgrade, which failed because of an error stating missing pms.msi. So I decided to just delete everything and start over.
That didn't work either. So I did the Microsoft Fixit. Plus did the Revo uninstaller. I then went into the hard drive and deleted anything related to plex that was still hanging around.
Still can't update/install. Same message.
I even did a restore on the whole computer to a week ago. Tried everything again (one step at a time trying to install). Nothing.
I've now realized that I know just enough about computers/programs to be dangerous and screw up my system more. Been at this for 2 days.
Any assistance would be greatly appreciated.
Attached are the most recent logs for the failed install.
