iTunes 9 installation error "Error getting file security"

Were you ever able to fix this problem? I am having the same error on my laptop (windows 7 OS). Thanks,

itunes installs quicktime. The trouble is with the security settings in the folder in C:\ProgramData\Apple Computer\Installer Cache.

On both the Apple Computer folder and the Installer Cache, you will need to take ownership. Then delete the quicktime folder.

First, to see the folder, in explorer go to Organize, folder options, then view tab. There click the radio button see hidden files and unclick hide protected system files.

Then navigate over to the folder location above.

Right click on the folders, click on properties, then security.

There at the bottom, click on advanced. Then click on the owner tab. There you can change the owner to the user that you logged on as.

That should fix it. Remember to delete the quicktime folder after to take ownership.
