I just downloaded the latest version of iTunes, however, the Apple Mobile Device Support program will not download. I have removed iTunes and re-installed it numerous times. When I plug my phone or iTouch in to my computer, it does not recognize it and tells me to uninstall and re-install the 64bit version. I have with no success. I am running Windows 7. I have followed all the advice I could find on the Apple Support site. Any suggestions or ideas would be greatly appreciated.

    Let's try a standalone Apple Mobile Device Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of why it's not installing under normal conditions.


    Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:




    Download and install the free trial version of WinRAR:




    Right-click the iTunesSetup.exe (or iTunes64setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").


    Go into the folder and doubleclick the AppleMobileDeviceSupport.msi (or AppleMobileDeviceSupport64.msi) to do a standalone AMDS install.


    (If it offers you the choice to remove or repair, choose "Remove", and if the uninstall goes through successfully, see if you can reinstall by doubleclicking the AppleMobileDeviceSupport.msi again.)


    Does it install (or uninstall and then reinstall) properly for you? If so, can you get a normal iTunes install to go through properly now?


    If instead you get an error message during the install (or uninstall), let us know what it says. (Precise text, please.)

    Thank you so much for replying to my question. I've been on a work trip and just got home to try to fix my problem. I did everything that you suggested, but to no avail. I got the error message: Error 1920-Service 'Apple Mobile Device' failed to start. Verify that you have sufficient privileges to start system services.

    The rest of iTunes installs fine, although when I was checking for errors, I noticed that Bonjour also had an error: Task Scheduling Error:m->NextScheduledEvent21725683.

    Thank you so much for all of your time and assistance in this matter. It's just nice to know that someone cares and is willing to help!

    It is not simple and I never found an Apple endorsed solution, but this worked for me.  Follow the directions very carefully:  http://randomwindowstips.wordpress.com/2009/12/08/windows-7-itunes-9-software-is -not-installed/

    Same problem here. Tried to install mobile device support stand alone using your steps, but got this error message:



    Hope you can help!

    Same problem here. Don't know what to do. Won't work, won't detect my phone, can't put on any files. Rendering my iphone somewhat useless at the moment.

    For those who still have this problem. There's an easy fix to this. Simply download the Mobile Device Support folder, extract it and replace it with the old one. If it doesn't let you replace it, simply rename the old one to anything i.e.(oldfile). Once you have renamed the old one, drag the one you downloaded into C:\Program Files\Common Files\Apple. Then re-run the installation and it should work perfectly.

    I'm getting a bit stressed out here, too. Had to set up my system from scratch for unrelated stepping-on-laptop-in-the-dark issues, and I am getting nowhere and nowhere fast.


    Here's what I've tried:

    Install iTunes - Apple Mobile Device was missing.

    Install iTunes, move old iTunes folder to new location - since Apple Mobile Device was still missing, it still didn't work.

    Install iTunes, import old folder - same

    Install iTunes with old folder in place - Old folder got integrated, Apple Mobile Devices got installed - iPhone was not recognized, because it "needed the latest version" of iTunes. Installing Upgrade failed.

    Install Apple Mobile Device manually as stated above (before and after iTunes installation) - Installation failed without explanation.


    I always uninstalled iTunes as per the instructions from this site. I'm running a Windows 7 64 Bit system with all the latest updates, freshly installed and running smoothly. In the course of all of these installations I have downloaded iTunes64setup many, many times. Surely in the double digits.


    If Apple at least let me install an older version, maybe that would work, but all I can find is always the latest.


    Samsung is sounding more and more promising...
