Crash/Burn - Need help w/ reinstall

I was in the process of updating the Plex Server when my computer locked up. After re-booting I couldn’t finish the install process nor uninstall Plex. I used the MS fixit program to no-avail. I tried CCCleaner to uninstall with no luck.

I have tried to remove Plex manually - deleting it and all mention of it in the registry. Still when trying to install it THINKS it’s still on my computer.

I don’t want to loose all of my data so I haven’t deleted the c:\users\appdata area yet.

Is there some way to force Plex to ignore the uninstall and just install?
