I'm not sure if it's a bug or just my system, but here goes.
If you run avedesk right after installing itunes, without running itunes not for once,
avedesk pops up this error messege telling you that it needs itunes original disk or something.
Avedesk will not load properly, and all you can do is to shut it off from task manager.
Reinstalling itunes + run itunes, then run avedesk solved the problem.
It was strange, just letting you know.
