What do i do? I've re-downloaded itunes 10.7 from the official website and re-installed...still same problem.

    Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)

     

    Let's try something relatively simple first. Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".

     

    If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

    Same exact problem.  Using Windows 7. 

     

    Restart did not help. 

     

    Control panel -- Programs & Features -- Apple Application Support -- then click "Repair"  ==> did not work.  Tried reboot after that too, and it did not work. 

     

    Any other suggestions?   would rather not reinstall all of iTunes 10.7 (since I can't even find iTunes 11 now to download -- at least not yet, I guess it is only available now through the update).

     

    Thanks!

    my exact message is:

     

    The procedure entry point avcfplayersetdirect3ddevice could not be located in the dynamic link library avfoundationcf.dll

     

    After I click ok, it says

     

    iTunes was not installed correctly.  Please reinstall iTunes.  Error 7 (Windows error 127)

    Tartikoff,

     

    Same thing happened to me. I simply uninstalled iTunes then reinstalled it.  Itunes remembered all the previous settings and recalled my entire music library etc

     

    Hope this helps.

    Update .netframework to latest version (see apple support)

     

    Follow the instructions on this link, basically un-install everything, remove programs that says they are made by apple inc. (using add remove program)

     

    http://www.reimageplus.com/fix-windows-127-error/   (Many thanks to reimageplus.com)

     

    You will also need to check and verify that the following folders have been removed:

    • C:\Program Files\Bonjour
    • C:\Program Files\Common Files\Apple
    • C:\Program Files\iTunes
    • C:\Program Files\iPod
    • C:\Program Files\QuickTime
    • C:\Windows\System32\QuickTime
    • C:\Windows\System32\QuickTimeVR

     

    dont forget to remove icloud also

    you dont need to delete your itune music library though

     

    If any of these folders still exist, delete them along with their contents. (if you cant delete them, right click and go to properties and then security and change the control of the fold to you)

    do this for files under  program files and program file (x86) on your computer

     

    once you have deleted everything, restart your computer. Then I repaired my registry using a registry repair program.

     

    Important:-  instead of installing itunes I installed quick time, which installs apple application support (this is the corrupt file which is causing all the issues)

     

    i then installed itunes and it all worked fine,

     

    should take no longer than half hour to fix

     

    hope this helps

    This worked (and all of my music is still there)! Thank you very much for your help and explaining your method so clearly - I had tried lots of other suggestioned techniques without success. A great relief to have my music back

    Hi, I have tried all of this and I still cant open itunes. I am running windows 8.1. Any help would be appreciated please.

    I have exactly the same problem. This after an "update" was installed and I had spent the previous day getting iTunes to work. If I may pose a question based on my long time experience: does Apple deliberately sabotage software for a Windows PC to try and get one to purchase their products? I have ENDLESS problems with iCloud, iTunes, Quicktime etc on my PC and the strange thing is I never experience problems on my iPhone or iPad. I am suspicious.

    No. Stuff happens. Sounds like you're sorted for now, but for anyone else having problems...

     

     

     

    For general advice see Troubleshooting issues with iTunes for Windows updates.


    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.

     

    Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
