I Have A PowerBook G4 and every time I Try to start iTunes it says :iTunes requires QuickTime 7.5.5 or later. For more information on upgrading your computer, visit http://www.apple.com/quicktime . If anyone could help it woould be appreciated.
PowerBook, Mac OS X (10.5.8)
QuickTime 7.5.5 for Leopard - http://support.apple.com/kb/DL27
QuickTime 7.7 for Leopard - http://support.apple.com/kb/dl761
= New version of Quicktime installed but application reports it needs to have that version installed =
Open Application > Utilities > System Profiler and check the Quicktime version in Frameworks vs. the version in Applications. One person had re-installed their operating system. It had kept the newer Player application but had reverted to an earlier version of the underlying support framework files which many applications utilize. Re-installing Quicktime 7.7 took care of the problem. Do this manually, not with Software Update.
Installation get stuck at "configuring installation" - https://discussions.apple.com/thread/2592979?threadID=2592979 - uninstall Quicktime before installing.
