What if the end user doesn have QuickTime installed?
QuickTime is always installed on a Macintosh. On a PC running Windows, if the user tries to install an iScreensaver that you created, and they do not have QuickTime installed, they will see a message with a button that takes them directly to the QuickTime website for download. Once the (free) QuickTime software is installed, they can continue installing the screensaver. Top of page.
