Enabled it, but when I restart MB, I get the following on restart
I don't think this should happen on restart. It's not enabled when MusicBee starts up, you have to go into the tools menu and turn it on.

That's confusing me, it's referencing the folder I have the source code saved in on my computer. I don't know why it's getting referenced on your system. But I'm mostly winging this project, I don't code for a living. Anyway, if it isn't obvious from the error it's having a problem initialising iTunes.
I have iTunes installed (have been using it to sync for years, but having trouble getting it to add new songs on Windows 11)
The file Interop.iTunesLib.dll is in the plugins folder (not under Program Files, but in C:\Users\...\AppData\Roaming\MusicBee\Plugins)
I don't have windows 11 and have zero interest in installing it so I can't help you with that aspect.
How did you install the plugin. What folders did you save the DLL's into?
You don't need interop.itunesLib.dll for this plugin to work.
In any case, it probably isn't an issue with the plugin install. I'd say it's an issue with the iTunes install on windows 11.
