After reinstalling OS 7.5 three days ago, and upgrading to 7.5.11 my iTunes won't work. A message tells me I must have Quicktime 7.5.2. My system has 7.2.2, dating from 2007. The Apple download center doesn't provide Quicktime installs. It informs users that Quicktime can only be installed along with a complete System. The System Preferences control panel screen for Quicktime isn't much help either. Clicking 'Update' takes you to a URL that no longer is online. Sooo, what does a guy do?
