  • Updating my Win7 to 12.1, I get 'iTunes was not installed correctly Error 7 (Windows error 127). If I try to launch, I get 'The procedure entry point "CMBlockBufferCopyDataBytes" could not be located in the dynamic link library CoreMedia.dll'. Help!

    Windows version 7. Auto update of iTunes to version 12.1 from 12.0.1.
    At end of install process, message 'iTunes was not installed correctly. Error 7 (Windows error 127).
    Tried to launch iTunes, anyway, but immediately got message 'The procedure entry point "CMBlockBufferCopyDataBytes" could not be located in the dynamic link library CoreMedia.dll'.
    Tried downloading iTunes and updating manually - get exactly the same result.
    No problem using iTunes before this.

    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 the 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.
    The error hints at a similar pattern to those discussed in the first and third boxes of the user tip, suggesting that you've got an outdated .dll file that needs replacing. You should find CoreMedia.dll in the one of the following folders:
         C:\Program Files\Common Files\Apple\Mobile Device Support
         C:\Program Files (x86)\Common Files\Apple\Mobile Device Support
    Delete it and then repair Apple Mobile Device Support from the Programs and Features control panel. If that doesn't work go for the full tear down and rebuild.

    which is a 64-bit installer for the 32-bit version of the core application, similar to previous 64-bit releases.

    Hi Molly - I can tell you're frustrated and I will do my best
    Can you tell me whether you have a 32bit or 64bit system. You can find out in the following way
    Windows Vista or Windows 7
    If you have Windows Vista or Windows 7, there are two methods to determine whether you are running a 32-bit or a 64-bit version. If one does not work, try the other.
    Method 1: View System window in Control Panel
    Click Start, type system in the Start Search box, and then click system in the Programs list.
    The operating system is displayed as follows:
    For a 64-bit version operating system: 64-bit Operating System appears for the System typeunder System.
    For a 32-bit version operating system: 32-bit Operating System appears for the System typeunder System.
    Method 2: View System Information window
    Click Start, type system in the Start Search box, and then click System Information in thePrograms list.
    When System Summary is selected in the navigation pane, the operating system is displayed as follows:
    For a 64-bit version operating system: x64-based PC appears for the System type under Item.
    For a 32-bit version operating system: x86-based PC appears for the System type under Item.
    If you have a different OS (operating system) let me know which one and I'll tell you how to find that out.
    Once I know I should be able to give you the fix.
    Cheers
