"Mobile Device helper has stopped working" after installing most recent

OK. Like a thousand other threads that have been posted over the past week or so on this topic and having tried most of the suggestions, I find myself at a loss.
After most recent update (which I installed on Monday) from 3.1.2 to 3.1.3 all **** has broken loose between my *iPhone, iTunes & Outlook*. This all came to light just hours after the install. . . . I noticed that my phone wasn't syncing - at all, it just "hung" there then I went into my contacts in Outlook - gone. . . UGH, EEK, OK, so they're still on my iPhone BUT I can't get to them in Outlook. After loosing most of yesterday and all of today I am at the mercy of someone who might know how to resolve this issue.
_*Steps I have taken :*_
I have un-installed and reinstalled iTunes 5 times, no luck, I've restarted, yada yada yada. I've hidden my Norton's Internet Security, allowed iTunes, etc. *Still no luck*. Take in mind, all was great after months of perfect syncing, etc. no problems whatsoever . . .
*The two messages that I continue to get when I open iTunes and connect my phone:*
1) "Mobile Device helper has stopped working"
2) " Unable to load data-class information from Sync Services. Reconnect or try again later".
The most recent error message under "Problems Reports & Solutions" on my start menu read:

Hi,
I have had the same experience... uninstalled and reinstalled iTunes and all Apple components only to now be in a position where I can't sync my iphone at all (before I started trying various solutions I could still sync music... now nothing!) and I continually get the messages "mobile device helper has stopped working" and then "iTunes was unable to load dataclass information from Sync Services. Reconnect or try again later".
I even tried reinstalling iTunes 9.0 but somehow I don't have the old library saved - means I lose all the ratings, playlists etc.
Really frustrating and disappointing.

  • Mobile Device Helper has stopped working

    I have just purchased an iPhone 3Gs, I have the lastest version of iTunes (9.1) and am operating on 32-bit Windows Vista using an Acer laptop.
    First, the iPhone was not recognised - so re-installed iTunes, downloaded Service Pack 2 for vista, reinstalled iTunes. Did't work. Finally found a forum that lead me to delete a problem file for Acer laptops (can't remember its name now) but then my iPhone was now recognised!
    Secondly, tried to sync my windows contacts (all my old contacta list from old phone) then had syncing problems..through more forums that error message stopped but now I have a new one that I can't get past...
    'Mobile Device Helped has stopped working' comes up repeatedly and will not let me to anything with iTunes as it freezes until I end task in Task manager.
    I have looked into other forums that talk of deleting the Apple Mobile Device, but it doesn't seem to me to be the rigt decision as the majority of people have just had to reinstall iTunes as it wont recognise the phone without the file.
    It seems that the new iTunes doesn't like Windows Vista.
    Please can anyone help me get past this point before I lose the will to live!! (it's been over 5hours now!!!!)
    Thanks

    Sort of the same issue.
    Windows Vista 64bit Home Premium.
    I just launched iTunes for the first time after installing 9.1. When I connected my iPhone, iTunes told me that I needed to install a newer version of Apple Mobile Device, which entailed removing/reinstalling iTunes and AMD. I remember there being an order to which applications should be removed, so I did that, but got stuck at AMD. I wasn't able to remove it. There was no error message, it just automatically rolled back the uninstall process and quit. I did some research and saw someone recommend using the Windows Install Cleanup Utility. I used that to remove AMD, and it worked. Next on the list was Apple Application Support (?), which also could not be uninstalled by normal means. So I used WIC on that as well. iTunes, Bonjour, Quicktime, and Apple Software update I was able to remove via the Control Panel. I rebooted, reinstalled iTunes, and when it began the install process for AMD I got this message:
    "Could not open key:
    Unknown\Components\DA42BC89BF25F5BD0AF18C3B9B1A1EE8\3F55235DF871F046A8F862841205 6EF. Verify that you have sufficient access to that key, or contact your support personnel."
    Got the same message for Apple Application Support. As a result, neither was installed.
    Prior to doing any of this, I had disabled AMD in Services, which didn't help. I have since re-enabled it, and it is still running in Services, although it does not show up in the list on programs to uninstall.
    After all this, I read in another forum that simply doing a Repair on AMD would solve the problem, but since I am unable to reinstall it, I cannot test it out.

  • PLEASE HELP!!! My 'Apple mobile device helper has stopped working'!

    Today i bought the new 3G iPhone so i went online to download the new 7.7 iTunes software. Now when i go into my iTunes a Windows pop up appears telling me that my 'Apple mobile device helper has stopped working' and that it is diagnosing the problem. The thing is that it doesn't diagnose the problem, the same box just keeps popping up over and over again.
    I am not very computer literate and have tried everything that i can think of but nothing has worked.
    Please can someone help because i'm absolutely dying to use my new iPhone; i queued up from 6 am to get my hands on it! :0(

    I'm just a simple user. I don't know how to fix it any more than any of the other posters with this problem. I've looked around in control panel, done some poking and prodding with services and processes, and can't find a reasonable way to stop the messages without completely hosing up iTunes. I know the messages are annoying as ****, and nobody likes the idea, but sitting around and doing nothing is sometimes a whole lot better then doing something that makes it worse. See if you can find a document from Apple that tells you how to go back to the previous version of iTunes. I've seen that course of action mentioned several times for previous releases of iTunes upgrades, so the instructions for it must exist in another forum.
    I just think, from the number of posts, that Apple is going to have to get a fix out pretty quickly, because this error pretty much shuts down their products on the Windows platform. They can't afford to let it go on for very long.

  • Apple Mobile Device Helper has stopped working - stuck in loop

    I keep getting a message/check box (AppleMobileDeviceHelper has stopped working)whenever I load iTunes under Vista. If I don't click and respond, my task bar gets cluttered up with these messages - I don't know what to do short of uninstalling everything.
    Any ideas of what else I can do to stop this box from coming up, so that I can use iTunes normally?
    Thanks

    You could try uninstalling Apple Mobile Device support using add/remove programs. I tunes doesn't require it and will work without it. However if you need it, try doing a repair install of iTunes which will reinstall Apple Mobile Deviced support.

  • Apple mobile device service has stopped working - continues

    Hi
    I have a 16GB iPhone with 02 in the UK.
    My first iPhone with 02 had trouble receiving calls with about 90% of incoming calls going straight to voice mail. I also couldn't backup that phone as every time I tried with iTunes, i got the message "Apple mobile device service has stopped working" about a minute into backup.
    This happened continually, I re-installed iTunes so many times, still with little luck. I tried a different cable too. All on a brand new Dell Vostro desktop PC.
    So, I took the phone back to 02 with these problems. 02 promptly replaced my iPhone.
    Now, I have exactly the same problem. I obviously have nothing to restore on the iPhone as I was never able to back it up in the first place.
    Every time I try and backup the iPhone I get the error "Apple mobile device service has stopped working". Again i tried a different cable and have removed and re-installed iTunes several times.
    Anyone any ideas?
    Regards
    D

    I was having this same problem with my new iPad 3G. It was driving me insane and preventing me from syncing the iPad.
    I removed and re-installed all Apple components from my computer as recommended (in the recommended order). But, the problem persisted.
    The error message looked just like the one posted above:
    Problem signature
    Problem Event Name: APPCRASH
    Application Name: AppleMobileDeviceHelper.exe
    Application Version: 16.691.14.1

    The SOLUTION came when i discovered that there were two copies of CoreFoundation.dll on my computer.
    One was in C:\Program Files\Common Files\Apple\Apple Application Support.
    The other was in C:\Program Files\Common Files\Apple\Mobile Device Support.
    I removed the copy of CoreFoundation.dll from the Mobile Device Support folder, and the problem vanished.
    I hope this helps.

  • Apple Mobile Device Service Has Stopped working

    Okay, I'm running 32-bit windows vista Buisness service pack one, and am getting the following message whenever I open iTunes: Apple Mobile Device Service has stopped working and was closed. This is not an issue connecting my iPod, which still connects fine, the issue arrises when I try to sync my new iPhone, and it is not recognized. Windows does recognize my iPhone, as seen in device manager and the fact that the phone charges when connected. iTunes will fail to recognize it due to the aforementioned error in starting itunes. The error log looks like this:

    I have gone through the basic troubleshoot on apple doing the following:
    restarting iphone

    sorry, i maxed out space in the last post.
    The steps I have taken to remedy the error are the following:
    restart iPhone
    restart computer
    check usp ports
    reinstall entire iTunes package(updater, iTunes, quicktime, apple mobile device support) several times
    I have also tried:
    -Running itunes as administrator, which I already am
    -restarting the apple mobile device service in services
    -checking for third party conflicts by having only itunes and the apple mobile device start when the computer starts and installing/running itunes with my anti-virus off.
    -updating AMDS(apple mobile device service) with older versions of the software from 8.1 and 7.7
    -deleting usbaal.sys from 8.2 and reinstalling 7.7 and 8.1 version
    I have tried various other fixes found online, In addition to spending two hours on the phone with various apple "experts" who were baffled by my problem.
    This problem is giving me the upmost frustration and I am becoming incredibly angry at both vista and iTunes. Please help
    -Kyle
    P.S. If you didn't catch it, i'm running the latest driver updates and the latest itunes, 8.2

  • Apple Mobile Device Service has stopped working. Vista SP2, iTunes 10.5

    Hi there. I've been having an issue syncing my iPhone to iTunes. Here's a description of the problem:
    -With an up-to-date Apple Mobile Device Service, error windows constantly pop-up saying that it has stopped working. If I close the error window, another one pops up fifteen seconds later.
    -If I plug my iPhone into my computer, it is not recognized in iTunes, because Apple Mobile Device Service is not running.
    -This error does not occur on my desktop PC, so I have been able to sync my iPhone by loading all of my files onto a USB and transferring them onto it. However, I would much rather not.
    Here are the steps that I have taken:
    -Uninstalled and reinstalled iTunes 10.5 with firewall off
    -Individually uninstalled and reinstalled the Apple Mobile Device Service with firewall off
    -Stopped and Restarted the Apple Mobile Device Service in Administrative Tools -> Services
    -Extensively searched the internet for solutions
    -Replaced Apple Mobile Device Service for iTunes 10.5 with Apple Mobile Device Service for iTunes 10.1 (This worked PARTIALLY. The error windows have now stopped popping up altogether, but I cannot sync with iTunes because the Apple Mobile Device Service is out of date. It asks me to update it, I agree, and I get the Apple Mobile Device Service that spawns error windows and still does not allow me to sync my iPhone.)
    I am running Windows Vista SP2, and iTunes 10.5. My Internet Security suite is AVG Internet Security 2011. My iPhone is running iOS 5.0.0. Here is a full report of the error:

    Just a shot in the dark, but have you downloaded any program from Megaupload, like MegaKey?  If so then that is your problem. I had been having the exact same problem for the past 2 weeks. I couldn't figure out what it was and tried everything that you have.. Then was on a board and someone mentioned Megakey. Having tried everything else, I uninstalled the program and reinstalled the current ITunes and AMDS. My Ipad and Iphone connected with no problem.

  • I am suddenly getting a message that the 'mobile device services' has stopped working on my computer and windows seems unable to fix.  I have tried finding the file and making sure that it is enabled.  It says 'enabled' but does not work.

    I recently downloaded a new update of the operating system on my 3GS  It seems to be a bit slower since and I have no idea if that is part of what is going wrong.  I cannot get itunes to recognise my phone.  Windows pops up a 'window' that says my 'mobile device services' is not working and would I like Windows to look online for the problem - I say yes, windows does it's thing, blanks out and I am back where I was.  I tried updating itunes but no luck.
    I found the mobiledeviceservices.exe file and made sure it was all 'on' and 'enabled' still no luck  I did a search and came up with some other people who had the same problem but the answers that they were given didn't help me.

    When you erased the disk did you select Mac OS Extended Journaled as the format option?

  • HP Power Advisor has stopped working after installing latest updates

    I have been using HP Power Advisor successfully on my Lenovo X230 running Windows 7.  After installing the latest Power Advisor updates it no longer works.  I can select a voltage from the dropdown on the Input Voltage screen but nothing happens when I click on the Go button, as if it is disabled.  I've tried re-installing the download package which works fine but it stops working again as soon as I install the latest updates.  Any ideas how to solve this?

    Well on the website for HP power Advisor, it specifically says, 
    "Accurately estimate power consumption of your HP server and storage products"
    There could be many different things interrupting your use of the program, but I'm going to say that maybe your largest problem with using the HP software designed for HP machines is your Lenovo.
    Sorry,
    Good Luck!
    Did I help you? Please give me a Thumbs up to help let others know!

  • Ethernet has stopped working after installing "Security Update 2010-003"

    I installed the update recently and have been unable to connect to the internet. The network still gives me an ip, but the internet and server button remain "orange". The wifi still works.
    Has this happened with anyone else? I am curious as to how I can either uninstall the update or make the ethernet work again..
    Much thanks for any recommendations you may have.

    Welcome to Apple's discussion groups.
    I'm not having that problem after installing the security update.
    If you open the Network panel of System Preferences and select the Ethernet connection item, is it set to "Configure" "Using DHCP"? Do you see reasonable values for "IP Address", "Subnet Mask", "Router", and DNS Server"?
