I downloaded and unzipped the current 3.1 file and tried to run the installer.
Immediately it starts I get this error:
Error opening file for writing
c:\Program Files (x86)\MuaicBee\MusicBee.exe
(and the the options abort retry ignore).
I've tried both running the file normally and using "run as administrator" and get the same error both times.
I'm on Windows 10, and my current MusicBee version is 3.0.6132
