You're not very verbal, are you? 🙄
It would help more if you could be more detailed in your responses. It's like we're doing all the work here, and you can't even be bothered to clearly explain what your problem is.
First, is your situation that you have iTunes running, and it refuses to quit because of this error, and you've kept it open because you're worried about this? Or is it that iTunes refuses to open?
Second, are you trying to change the permissions of the library file while iTunes is running, or while it is not running?
Third, if you want to delete the file, have you tried it while iTunes is not running and after making sure that the permissions are as described in my post? If that doesn't work, what is the error? And who is listed as the owner of the file in the info for the file?
