SC Tom
I have a similar problem as first mentioned above. However, I do not have the windows 7 disk (it already came installed on the new laptop that i just purchased). What can I do? I can't uninstall anything, and I have problems downloading itunes where I get the message that "windows installer could not be accessed". when i try to search for this program under start-->search, nothing comes up. Any help would be greatly appreciated!
