Installing/Updating iTunes 12.1.x 64bit Error 7

Every time I try to install or upgrade iTunes on Windows 7/64 to any 12.1 version, the Apple Mobile Device service fails to start every time. If I hit ignore, then let the install complete, I get a permanent "Error 7" message any time I try to start iTunes.
If I reboot, I get the same errors plus several other applications are broken and have to be reinstalled.
I've had to go back to 12.0.1 and now everything works fine again.
What have apple done to 12.1 since going full 64-bit?

    Hi Jen.  My daughter just compleated her nursing program and is now working as a full time nurse.  Focus and study hard and soon you will be there too.  Now to the problem at hand.  I have the same problem.  I gave up on it and satisfied myself with my iPod without the upgrade.  Reason being I've read so many posts of people having problems after the upgrade.  But I'm sure other factors are involved.  Nevertheless here is the fix most say works to solve the problem:  What ever virus protection you have installed on your computer, disable it.  Then try to install the update. After that enable the protection. I had Kaspersky, and it does it's job well. The thinking is, the virus protection is blocking the upgrade.  Hope this works.   Charlie

    (1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    (2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
    (3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
    (4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
    (5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

    hello!
    i have a similiar problem:
    i upgraded my mac from 10.6.8 to 10.7.something recently, but i did NOT update itunes, still running version 10.4.1. now i wanted to open itunes but it tells me, that my iTunes Library.itl was created by a newer version of iTunes - which i never used!

    Okay.
    I'd first try downloading an installer from the Apple website using a different web browser:
    http://www.apple.com/itunes/download/
    If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

  • Why I can not install the iTunes to my new 64bit laptop??? I have never had this kind of problem before on my 32 bit old laptop...

    I would like to get a help... I can not install the iTunes to my new (64bit) laptop... Why??? The installation stops somewhere after a few minute, looks like trying to install but can not go through until the end. I had my old (32bit) laptop and i have never had any problem with the installations... My new laptop is Asus (64bit), and the operating system just upgraded from Win8 to Win8.1....

    Hello rafaelfromweymouth
    Start with the first article and clear out any files in the Temp folder. You may need to remove iTunes and its related software and finally make sure that you have the 64-bit version of iTunes downloaded to install.

  • Updating iTunes 12.1 and get error message "The procedure entry point CMBlockBufferCopyDataBytes could not be located in the dynamic link library CoreMedia.dll - what went wrong and how to resolve this?

    Updating iTunes 12.1 and get error message "The procedure entry point CMBlockBufferCopyDataBytes could not be located in the dynamic link library CoreMedia.dll". What went wrong and how to resolve this?

    Entry point errors can often be fixed by deleting the offending dll, then repairing the component it is part of.
    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 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.
    If the advice above doesn't resolve things you could try this alternate version:
    iTunes 12.1.0.71 for Windows (64-bit - for older video cards) - itunes64setup.exe (2015-01-28)
    which is a 64-bit installer for the 32-bit version of the core application, similar to previous 64-bit releases.
    Or roll back to the previous build:
    iTunes 12.0.1.26 for Windows (32-bit) - iTunesSetup.exe (2014-10-16)
    iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16)

  • When I try to update iTunes 10.3, Insufficient Privileges error. C:\programData\{429CAD59-35B1-4DBC-BB6D-1DB24-6563521}\x86\DIFxAPI.dll

    When I try to update iTunes 10.3, the installer finishes downloading but then this message appears "errors occured while installing updates. If the problem persist, select Tools, "just download" and instal them manually"
    so I go and do that, select Tools and then just download. Then when it finishes loading it goes back to the Apple Software Updater and pups up another window at this location C:\Users\brandsmart\AppData\Local\Apple\Apple Software Update
    there I find AppleApplicationSupport, AppleMobileDeviceSupport, Bonjour, iTunes, QuickTime and SetupAdmin. So when I select iTunes it starts downloading it again, but this time as if it was the first time (not an update)..
    It takes me to "Welcome to the iTunes Installer" I click next, I accept the terms and conditions and click next, takes me to the "Installations Options" I check and click "Install" then click "accept" then "accept" again, so it starts to download but then when it finishes downloading this meassage appears "the installer has insuffisient privileges to modify this file: C:\ProgramData\{429CAD59=35B1-4DBC-BB6D-1DB24-6563521}\x86\DIFxAPI.dll.
    and there are three options- "Abort, Retry and Ignore." If I "ignore", nothing happens, just closes and pups right back up. If I click "retry," just the same, closes and opens right back up with the same options. If I "abort" it asks me if I'm sure to cancel, so I click "yes" so it says "rolling back action." when it's done it just closes everything and if I try to update, it's the same story all over again.
    If I go to the "Advanced Security Settings for iTunes" I can see my name and two more options, all of them say "allow and full control" so I'm guessing that's not the problem but I don't really know.
    Please somebody help me!! I don't know what to do.

    the installer has insuffisient privileges to modify this file: C:\ProgramData\{429CAD59=35B1-4DBC-BB6D-1DB24-6563521}\x86\DIFxAPI.dll.
    That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
    Vista instructions in the following document: Check your hard disk for errors
    Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors. You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
    Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?

  • HT1926 when updating Itunes on my computer an error message appears stating that itunes update cannot be completed because there is a program missing.  What program is it that itunes needs?  I am currently using windows xp.
