User's security level issue

Question

I have an Administrative and a Limited User accounts on my PC. iTunes works fine under the Administrative account, but in Limited User account I get an error everytime I try to change some kind of configuration option at Preference's window (Edit/Preferences). I think iTunes should store the configuration file at user's account folder.
The other problem on my Limited User account is that I'm no longer able to add musics on iTunes. I use the "Keep iTunes Music folder organized" and "Copy files to iTunes Music folder when adding to library" options. WHen I try to add a file, iTunes show an error like "Attempting to copy to the disk 'C:\' failed. The disk could not be read from or written to.". iTunes is configured to store all my musics at an folder like C:\MP3 and even my Limited User account has Full Control to this folder.

Answer 1

Limited user accounts have limited access to folders, I think if you want iTunes to work in a limited access account accessing a folder outside it's own account you will probably need to adjust the the permissions.
This should be straight forward in XP Pro. You need to set the folder permissions so the limited user at least has write/modify access and preferably full control of the iTunes folder and iTunes Music folder.
You can do this from the security tab in the folder's properties.
