"The Installer has insufficient privileges to access this directory: C:\Documents and Settings\All Users\Application Data\Apple Computer\Installer Cache\iTunes 9.0.3.15. The installation cannot continue. Log on as administrator or contact your system administrator."

First I tried to update iTunes and quicktime and it wouldn't finish and now when I try and open itunes I get that msg. It tries to install itunes. Now this has happened to me before when I updated to itunes 9 and I found somewhere on this site where it told me I needed to delete some folder and then reinstall the newest version of itunes and that worked. Does anyone know which file or folder I need to delete to get back in business here? If you have any other solutions I'd be glad to here those as well, but I cant take much more of not being able to listen to music. Thanks.

PS. I am the administrator of this computer obviously, so....

    Hi Cryptorchild.

    I was up for over 12 hours trying to solve this problem. I followed all of Apple's instructions on the topic which included uninstalling itunes and quicktime which were initially unsuccessful because of the privileges issue you mentioned. However after many uninstall attempts i decided to restart my machine and when it rebooted quicktime was gone.
    i found out that uninstalling quicktime/itunes was not the problem however. When you get the insufficient privileges error, go to the location where it says it can't get privilleges. Then right click it in the left window pane and select properties.
    Open the security tab; i cant remember exactly how but it's absoulutely essential that you give yourself the 'special permission' ability in here. Just look around in advanced settings and you will find it.

    Once i did this i tried quicktime again and it installed, accordingly so did itunes. Hope this helps, a lot of people have been having trouble with this since itunes 9 was released.
    Apparently it's something to do with Microsoft trying to get people away from using quicktime.
    Best of luck.

    Why "obviously"?
    Simply because you are the only user does not mean much.
    Are you actually logged in with an administator account?
