  • I was today invited to upgrade my iTunes when I logged on.  Update failed. Every time I now try to open iTunes I get error messages.  Second message reads "iTunes was not installed correctly. Please re-install iTunes. Error 7. Windows error 126"

    I was today invited to upgrade my iTunes when I logged on.  Update failed. Every time I now try to open iTunes I get error messages.  Second message reads "iTunes was not installed correctly. Please re-install iTunes. Error 7. Windows error 126". I now can't sync my iPhoneand I am worried that if I re-install I will lose all my contacts,calendar, notes, etc.

    I too had this problems (Windows 8.1).  A few weeks ago after the previous update before this version of itunes, I'd had a problem with the itunes store crashing and at that time I followed instructions to copy QTMovieWin.dll to the itunes folder, which fixed the store crashing.
    Today I fixed the problem by:
    Delete QTMovieWin.dll from C:\Program Files (x86)\iTunes.
    Uninstall ALL Apple Software using Control Panel / Programs and Features.  I uninstalled:
    iTunes
    QuickTime
    Apple Mobile Device Support
    Apple Application Support
    Apple Software Update
    Bonjour
    Delete the folders:
    C:\Program Files (x86)\iTunes
    C:\Program Files (x86)\Common Files\Apple
    Restart the computer
    Reinstall QuickTime
    Reinstall iTunes
    Everything works GREAT now, including the iTunes store.  You will not lose your media files, I got everything back, all my settings, playlists, etc.

    Saw this solution on another post about an iPad in a school enviroment. Might work on your iPad so you won't lose everything.

    ‘iPad is disabled’ fix without resetting using iTunes
    Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
    I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
    Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
    1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
    2. Open iTunes with the iPad disconnected.
    3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
    4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
    5. Click ‘Setup as new iPad’ and then click restore.
    6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
    7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
    8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
    If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
    ~~~~~~~~~~~~~
    Try it and good luck. You have nothing more to lose if it doesn't work for you.

  • When updating itunes I get the message the install package can't find a file (itunes.msi) I've searched but can't find this file.  How do I install it?

    When updating itunes I get the message the install package can't find a file (itunes.msi) I've searched but can't find this file.  How do I install it?

    Download the Windows Installer CleanUp utility from the following page (use one of the links under the thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    To install the utility, doubleclick the msicuu2.exe file you downloaded.
    Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
    Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?
