If you receive this error while trying to install or upgrade iTunes, please download this file. This is the Microsoft CleanUp Tool. It will remove all of the various left over things that iTunes has somehow corrupted or could not remove.
Install the program.
Run the program and look for iTunes or anything related Apple as well as QuickTime. Remove those items and try the installation again. This should fix the problem.
Access is denied when I try to run the program, any suggestions?
Thx u very much!!!!!!1
