Not Enough Access Privileges?

Odd.

If you right-click on the iTunes desktop icon and select "Run as administrator" does the application open?

Okay.

In other contexts (usually when trying to close itunes), that sort of message can indicate security software interference with iTunes library read/writes. You might possibly have something similar going on.

What security software do you have installed on the PC? (Firewall, antivirus, antispyware?)

That does some real-time scanning, so possibly it might be locking down your iTunes.

By way of experiment, try disconnecting from your network and/or the internet. Now disable all your Avast functions, and try launching iTunes again.

Do you get the same message, or does iTunes launch under those circumstances?

(Reenable all security software prior to reconnecting to the internet and/or your network.)

Okay. Probably not the security software then.

By way of experiment again, try creating a new user account with full administrative rights on the PC. Log out of your usual account and log into the new one.

Try launching iTunes in there. Do you get the same message in that account too? Or does the iTunes setup assistant run and eventually open iTunes for you?

(Trying to work out if something has gone amiss with folder and file permissions for your usual user account here.)

Isn't there any quick solution for this?

If anyone here knows precisely what is going on with Lilrobby's particular error message in this context, and can cut to the chase with a guaranteed solution, please feel free to leap in. I'll withdraw from the troubleshooting.

hey i had the same problem but just right click the itunes icon go to properties then click on compatibility and all the way n the bottom theres a box that says run as admin... check it and it will let u run it

The solution for me:

1. Check your default music folder permissions. Sometimes, Windows 7 locks you out of some of your own folders.

2. If you do not have access, right click the folder and give yourself all permissions.

2.1. You can also download a little applet called "Take Ownership". This will allow you to take ownership of all sub-folders and files.

3. Start iTunes. Everything should work now. Too bad the error message is so cryptic.
