Problems running 10.9.x releases

Code:

with working directory 'C:\Program Files\Jellyfin\Server\jellyfin-windows-tray'. Access is denied.

This leads me to believe that your environmental paths for Jellyfin that's overriding the defaults.

1. In the start menu or a run box type “sysdm.cpl” and open that up.
   
2. Navigate to Advanced -> Environment Variables
   
3. In User Variables- click path, then choose edit. If there is a path for jellyfin, then delete it
   
4. Do the same thing for the System Variables.
   
5. Restart system.
