Hello, I recently tried to update iTunes and QuickTime on my parent's computer. However, every time I try and update both programs, they simply stop halfway through their installation. I get some error each time that pops up with this: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\... I've tried to get into the file, but I can't gain access to it. I have also tried to unistall iTunes and Quicktime, but doesn't seem to matter. Any help would be appreciated.
