    @DJScottyD : no, doesn't help.


    The problems I'm having with 11.2.32 are linked to a large library.


    The "trick" with copying the Quicktime DLL didn't help as well.


    I already submitted a report to Apple, hopefully they will pick this up. For me at the moment:


    11.1 = OK with large libraries (> 500 GB) and Windows 8.1 x64

    11.2 = NOT OK with large libraries (> 500 GB) and Windows 8.1 x64


    11.2 after a fresh install works ok, even with some songs in your library. I didn't check where things go wrong.


    I have seen similar reports on the OS X side of things, so perhaps it's in their database code.


    Makes you wonder.. whether they test these "performance optimizations and bug fixes"....

    I have the problem too since upgrade my nb from WIN8 to WIN 8.1 .  Even I have update my itune to latest version, it still can't recognize my ipod nano 7th gen and my ipad mini.  What's going on?

    Has anyone tried restoring back to Windows 8? Seems to me a logical solution until Windows 8.1.x comes out to fix various issues.

    Re the signing in and agreeing the licence problem, this thread has some tips:


    I've just tried the tip on re-authorizing your already authorized computer, and that may have worked...,


    Yes: having both exited and restarted iTunes, and then rebooted my laptop and restarted iTunes, I can say that re-authorizing my laptop in iTunes has definitely made iTunes remember who I am.  (Presumably until the next update when everything will go Pear-shaped again.)

    I am delaying upgrading to Windows 8.1 until Apple brings out an iTunes update to be fully compatible with Windows 8.1.

    This solved my problem also.


    Thank you!

    I found the solution on another website.

    Copy QTMovieWin.dll from:

    - C: \ Program Files (x86) \ Common files \ Apple a \ Apple Application Support

    And paste in the file :

    - C: \ Program Files (x86) \ iTunes

  • section2i Level 1 Level 1 (0 points)

    Tell a lie.  Re-authorizing DID NOT WORK in the long run.  Sorry everyone.  

  • Loek Frederiks Level 1 Level 1 (15 points)

    All the solutions above, incl. copying the DLL, are nonsense.


    I am using iTunes 11.1.3 with Windows 8.1 x64 and it works fine, even with a huge library (> 500 GB). I also have QuickTime installed. AFAIK, in the past iTunes came with QuickTime. Wouldn't be surprised if iTunes is using QT components for playback of AAC, MP3, Audible files etc.


    I also had to authorize my PC again, but that was more related to the fact that the Windows 8.1 upgrade made to reconsider/redo the hack I made to move my User profiles away from the C drive to the D drive (C drive is a SSD). In order to undo this before upgrading I only managed to partially copy my old profile incl. iTunes library back to the C drive.

    Running Windows 8.1 x64


    Uninstalled, and reinstalled iTunes - no change.


    Then followed the steps in this tech support bulletin:



    confirmed that the computer recognized the apple devices - noticed that the devices were attempting to use a realtek driver upon open. Followed the bulletin steps to reinstall the Apple Mobile Device USB Driver. Had to connect both the iphone and ipad individually to reinstall. Everything working as it should now.


    Good luck - hope this helps you!

  • CJL2012 Level 1 Level 1 (0 points)

    Sorry - should have been a little more clear...


    my computer recognized my iphone 4S only a picture storage device - but itunes could not see it, and the computer only recognized the ipad as a storage device - and also not in itunes.


    using the correct drivers put everything back together again - and itunes recognizes them.


    too bad fixing the obamacare website isn't this easy!!!

    I rarely find helpful answers in here so thank you - this worked for me as well on iTunes

    My huge problem is ,that I cannot even download itunes.I trried many times,it always says :Itunes64setup.exe cannot be saved,because the source is unreadable.


    What should I do now?

    Does anyone know?

    I've only just updated from Windows 8 to 8.1 yesterday and everything is working fine. No issues at all with iTunes, I'm still on iTunes All my Apple devices sync as per normal - iTunes is always on and haven't experienced any crashes or other issues. Guess it was a matter of time for Windows 8.1 updates getting things right.
