Yesterday, I upgraded to iTunes 9 x64 (running Windows 7). The installation went fine and iTunes seemed to be working great until I plugged in my iPhone. When I plug it in, rather than showing up under my devices, I get an error message popping up:

iTunes requires a newer version of Apple Mobile Device Support. Please uninstall both Apple Mobile Device Support and iTunes, then install iTunes again.

( picture: )

I have tried to uninstall the Apple Mobile Device Support with little success and tried running the repair for the iTunes install, but I still have failure. I am worried about losing all of my iTunes data if I uninstall - I recently switched over to a different OS installation and copied my iTunes config information (XML docs and stuff) - it kept my library intact, but sneakily reset my iPhone to a way old configuration and deleted most of my data from it.

So... (1) has anyone else run into this and overcome it, and (2) how can I follow the directions [uninstalling/reinstalling] without losing my data, computer authorization with iTunes, etc.?


Custom-built PC, Intel Core 2 Quad Q6600, 8GB RAM, Other OS, Windows 7

    No helful information for you im afraid but i have just upgraded to iTunes having firmwared my iPhone to 3.1 and am getting the same issue.

    My PC is a recently rebuilt 32bit Vista installation which has untill now been running without issue.

    I did notice when installing iTunes, it seemed to take ages to install and at one point performed a "roll-back" before completing "successfully".

    Information on the forums points to other people having this issue in the past with no further assistance from apple and winding up rebuilding pc's

    I am having the EXACT same problem. I'm running Windows 7 (RTM), install iTunes 9 and then I get the same error when connecting my iPhone.

    I've tried uninstalling/reinstalling everything Apple with no success.

    I just upgraded my Itunes and am now getting the same error message. I too am running Windows 7 Ultimate RTM. I haven't tried uninstalling/reinstalling yet. I will try it tomorrow when I get home from work, if nothing else has turned up in the forums.

    Please post if you find a fix.

    It was suggested to me that I try installing the latest version of the iPhone Configuration Utility (2.1) ionutility21forwindows.html

    The installation took forever and then bombed out at the end.

    Here's what worked for me:
    1. Uninstall Apple Mobile Device Support (AMDS).
    2. Restart computer.
    3. Repair iTunes v9 install. (This should reinstall latest AMDS.)
    4. Plug in iPod.

    If that didn't work for you then:
    5. Repeat 1 & 2 if AMDS present.
    6. Uninstall iTunes v9.
    8. Reinstall iTunes v9. (No data should be lost.)
    9. Plug in iPod

    P.S. BTW, I also disabled my COMODO firewall just in case this caused the original problem with the AMDS iTunes 9 install.

    Ok, here is what seems to have worked for me. I was not able to uninstall AMDS from the control panel, because it was generating a fatal error. I then stopped all apple related services, and then did a repair installation. This allowed me to uninstall AMDS, but when I went to repair didn't reinstall AMDS.

    I then uninstalled everything related to Apple, Itunes, Bonjour, Apple software update, Apple application support, the Iphone Configuration utility. I then installed Itunes 9 from the downloaded file, and it opened fine. I then connected my iphone and it synced fine as well. It's downloading the 3.1 firmware now and I will disconnect and reconnect once that is installed to make sure it's all still working.

    Hopefully this works for the rest of you.

    p.s. I didn't reboot at all during the uninstall of all services and reinstall.

    I have the same problem as everyone else here. I have Vista 32 and none of the advice here has worked for me. I've spent hours on this now. It's very frustrating.

    Thanks for the advice, but I'm interested to hear any other ideas. Thanks!

    I wound up getting it to work by doing a system restore and trying again. I know it's not the answer anyone wants to hear, but it worked for me.

    I just disconnected and reconnected my iphone several times and it has not generated the error again. Itunes now opens when I connect the iphone too, which wasn't working before in Windows 7.

    Hi Guys. Listen to what worked for me
    - Go to Control Panel/Administrative Tools/Services/ and stop Aple Mobile device service from running
    - Then go to C:\ProgramData\Apple\Installer Cache and delete all previous Apple Mobile Device Support folders that contains installation archives
    - Extract AppleMobileDeviceSupport.msi from iTunesSetup.exe using WinZip or anything else
    - Run the msi et voila Everything works fine when you open Itunes and connect your phone or pod

    I suppose that the existence of Installer cached items wouldn't let the installation included in iTunesetup.exe to complete
    Hope it ill work for you

    I have Windows Vista 64 bit and Apple Mobile Device support will not install no matter what. It gets to the end of the "copying new files" stage and then starts the "rolling back action" and ends saying "the installer encountered errors before Apple Mobile Device support could be configured."

    All of the other components of iTunes 9 installs just fine but without AMDS I can't connect my phone. I've tried everything posted so far and no luck. Looks like I may be stuck going back to iTunes 8.

    Worked beautifully in Windows 7 7100. One more note to extract the files you need.

    *Start - Run*

    *C:\Path\To\iTunes64Setup.exe /extract C:\Any\Path*

    You could use %TEMP% for any path if you want.

    Nice work manu214
