    Newbie here... hoping someone can help with the itunes issue I'm having;
    Using a 2005 powerbook, 10.4.11
    Recently installed an auto software update that included an itunes update.
    once updated, itunes will not open. comes up with 'This copy of itunes is corrupted or not installed correctly. Please reinstall itunes'
    I have downloaded the latest itunes and tried various times to install however install gets close to complete then states the install fails due to a corrupt file.
    Naturally I don't want to loose all the songs and videos accumulated in itunes..
    Can anyone assist??
    I've also looked to clear caches in Library/caches etc but nothing I've tried seems to fix.

    Try to repair disk permissions with disk utility

    Did you try starting in safe mode?
    Hold shift key while restarting

    Did you try to open up a new user?
    The ditch old user profile

    Throw out itunes.plist Preferences file

    Download Pacifist and re-install itunes via the package

    Plenty of choices.

    Removing iTunes for Mac OS X

    By the way, you do know that your iTunes library, where all your movies and music are held, is external to the actual iTunes application right? Removing iTunes from the computer is not going to delete your media content.

    All recent versions of iTunes backup your library by itself when updating.

    Library backup is located at:
    useraccount/music/itunes/Previous iTunes Libraries

    1. Go to useraccount/music/itunes
    compress "iTunes Library" (to backup) and put "iTunes Library" in the trash.

    2. Go to useraccount/music/itunes/Previous iTunes Libraries
    and COPY (not move) the most recent "iTunes Library 2010-xx-yy" file into

    3. Changed copied "iTunes Library 2010-xx-yy" file into "iTunes Library"

    That should be it.


    If that doesn't work, use AppCleaner to uninstall iTunes.
    Then download / reinstall latest version.

    If it doesn't work you might have to
    iTunes Music Library.xml
