    Coremedia.dll

    I tried to upgrade to ITunes 12.4.3.1 on a work PC, Win7 32-bit. Program hangs with no explanation.

    I did an uninstall/reinstall with Revo Uninstaller, restarting the machine, then tried installing an older version of ITunes. In each case, I get an error message referring to the procedure entry point CMTimeRangeMakeFromDictionary could not be located in DLL Coremedia.dll.

    That DLL is in two places in my PC. Using regsvr32 to unregister and reregister does not work.

    Two questions, why would ITunes 12.4.3.1 dislike a benign PC and if it does, how do I get around this. Older versions did work, now I can't even get them to work.

    Thanks!!!

    Try re-installing just the Apple Application Support (which is responsible for installing Coremedia.dll).

    1. Use Disk Cleanup (cleanmgr.exe) to clean up temporary files.
    2. Re-boot.
    3. Turn off any AV protection temporarily.
    4. Unpack the iTunesSetup.exe installer. (I used 7-Zip tp unpack the installer into a folder.)
    5. Use the AppleApplicationSupport.msi to re-install just the Apple Application Support.

    Hope this helps...

    Thanks

    This tech gets all sorts of thoughts and ideas. Thank you for yours.

    Just for the hell of it, I reinstalled the current version, 12.4.3.1. It still hangs when I log in with my own account. But on the same PC, with a different user account, it works. Obviously a profile issue.

    So I can delete (brute force) my profile on the PC, then log in again and Itunes should work on my login. Before I do that, I will try a cache emptying first from IE. Granted, this is ITunes, not IE, but you never know


    How does that sound?

    The way you've described it, it does sound like a profile issue.
