Just re-installed but didn’t backup the registry. Oops. Don’t panic.
First, as long as you have your Plex Data stored elsewhere…
- Setup your new server to use the old plex data location on your hard drive.
- Restart Plex. You should see your libraries. You’ll also see your NEW library in the settings, and you will see your OLD server, but it will be offline.
- Click on your OLD (offline) server.
- The URL will look something like:
http://127.0.0.1:32400/web/index.html#!/settings/server/bed6fbfe0486fcbfb1a845c8f5aeec4ab545903b/settings/general - Grab that ID string. Shutdown Plex media server.
- Open REGEDIT, and hit up Computer\HKEY_CURRENT_USER\Software\Plex, Inc.\Plex Media Server and change the values for “ProcessedMachineIdentifier” to the string above.
- Start Plex Media server. Enjoy.
