iTunes does not open on Windows 7

Recently, I was helping a user whose computer wouldn't launch iTunes. This user had Windows 7 64 bits and I had already uninstalled iTunes and reinstalled the newest version of iTunes from the Apple site and yet the issue persisted. I had noticed that iTunesHelper.exe was running and that the process itunes.exe would also quickly launch and close itself so that told me there were some incompatibility issues with some other app or a service was not running.

Believe it or not the solution was uninstalling Quicktime! It looks like that computer had an old version of QuickTime that was no longer compatible with iTunes. After I uninstalled QuickTime, iTunes worked perfectly!
