Apple QuickTime 7.6.2 for WIndows XP/Vista
QuickTime 7.6.2 includes changes that increase reliability, improve compatibility and enhance security. This release is recommended for all QuickTime 7 users.
Installing QuickTime 7 or later will disable the QuickTime Pro functionality in prior versions of QuickTime, such as QuickTime 6. If you are a QuickTime 6 Pro user and you proceed with this installation, you will need to purchase a QuickTime 7 Pro registration code in order to regain QuickTime Pro functionality.
