Apple Mobile Device Service Stopped Working 8.2

Ugh. I know there have been many posts on this, and I've tried all the suggestions, but nothing has helped.
I'm running Vista Ultimate x64. I upgraded to iTunes 8.2. The second it finished installing, I got a message that said "Apple Mobile Device Stopped Working and Was Closed". The computer recognizes my iPhone, and there are no errors in the device manager, but iTunes says "iTunes can not sync with the iPhone because Apple Mobile Device Service is not started. Here's what I've done so far:
I added application exceptions for everything in the Apple Mobile Device and iTunes folders to my Norton 360 firewall.
I uninstalled everything Apple related (including mobile device service, bonjour, etc), cleaned my registry and re-installed 8.2.
I uninstalled again and went back to 8.1 The mobile device service worked, but when I opened iTunes I got an iTunes message that said "iTunes can not open ituneslibrary.itl because it was created by a newer version of iTunes."
I uninstalled, reinstalled 8.2, uninstalled just the mobile device service, and installed just the mobile device service from 8.1. Everything was fine until I opened iTunes and got an error message that said "iTunes recquires a newer version of Apple Mobile Device Support. Please upgrade".
So at this point it looks like my options are: Go back to 8.1 and start over with a brand new library (which is a huge pain because I've got over 300 gigs of music and at least 50 playlists that I use for my work) OR stay with 8.2 and not be able to sync my iPhone (also a huge pain because, well, I need to be able to sync).
Here's the log entry in my Event Viewer every time the "Appple Mobile Device Stopped Working" error pops up: "Faulting application AppleMobileDeviceService.exe, version 2.50.39.0, time stamp 0x49f9b7cf, faulting module RPCRT4.dll, version 6.0.6001.18051, time stamp 0x48002cd4, exception code 0xc0000005, fault offset 0x00018092, process id 0x14d8, application start time 0x01c9e9f70b1e30ad."
Does anybody have any ideas? Does it have something to do with my system being 64 bit and where iTunes installs its drivers and such? Is there another update coming soon, Apple?
Thanks,
Matt

Stay with itunes 8.1 - sounds like that was working for you.
Get the itunes database file for itunes 8.1 out of the *Previous iTunes Libraries* folder.

Doublechecking, m. When you did your iTunes reinstall, was it a complete uninstall/reinstall as per the following document?

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.

"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.

*i've managed to download quicktime, but am still unable to download itunes. after reaching a certain point in downloading itunes, (about 1/3 of the way?) it stops at "copying files", and my computer freezes and i have to hold the power button in order to shut it off and do anything, or i get a popup asking me if i want to change something so itunes can finish downloading. i click "yes", but then the download stops completely and i get a message saying "itunes has finished downloading, but with errors" and it tells me to download it again.
a popup from MobileServiceDevice keeps appearing as well, but it won't go away. the details are:

but the fault module name changes on me. sometimes it's kernel32.dll, and sometimes it's something else, and i've already tried using task manager /find str but it doesn't help.

Apple Mobile Device Helper Failed????!!!???

I tried downloading the new itunes and the new software for 2.0 and downloaded both fine but now every time i start itunes i get a message saying apple mobile device helper has failed and it will not sync or recover my phone, my phone was bricked til i recovered it on my old computer, now it seems to be working ok, but i dont have any new software. Also my new computer can not run itunes because everytime i do run it i get a message saying the helper has failed every 20 seconds or so, i want to update everything on the new computer (with vista home premium if that matters)but dont want my phone to brick again, any suggestions? already tried reinstalling itunes, and i can get the message to stop if i uninstall the apple mobile device helper but then my phone will not sync, also i have the original 8gig if that matters, thanks in advance for any help

You can go to "C" drive, Program Files, Common Files, Apple, Mobile Device Support, Bin and remove AppleMobileDeviceHelper.exe file -- that will stop that message from poping up.

Apple Mobile Device Helper quits at startup-iTunes won't run.

The last two times I have started my computer the Apple Mobile Device Helper suddenly quits and I can't open iTunes. I tried to download iTunes again but the download consistenly stopped up at 17%. I don't know what's wrong. iTunes worked fine yesterday. Please help!

Okay, so the same thing is happening to me. I do not have a Mac.
I uninstalled that Apple Device Mobile Support but I don't think that helped at all.
I don't really know what I'm doing.
Everything I plus in my iPhone it doesn't pop up in my iTunes.
Please help!

When I conect any ipod ,the itunes show an error msg-The syncServer found a problem and must be closed.After that another-Mobile device helper find a problem and must be closed -and this repeat more 2 times each are related with corefoundation.dll.

Six error msg about apple aplications that must be closed just when I connect my ipod to computers USB.SyncServer aplication and Mobile device helper is closed.The error relat.show :
AppName: syncserver.exe AppVer: 17.641.14.26 ModName: corefoundation.dll
ModVer: 1.550.54.0 Offset: 00043d08
These happens in both kind of messages that was showing three times each.After this ,Itunes can sinc music videos,photos,but I canot upgrade my ipod!
Detail:copy photo files from ipod to computer works normal.I use panda antivirus but without it in the computer,the problem persists.Yesterday I get the last ITunes,but the problem persists.I unistall anything about apple ,install the new Itunes and the problem remains.
And this problem occurs only after I connect ANY ipod to the computer,open Itunes for hear music,for example,still works OK.

I have been battling against the same issue for over 2 weeks now. After tracing what was happening on the machine to find that the crashes we're happening slightly after Apple's program we're identifying the Time Zone of the computer, I had the idea of checking the date/time properties of my Windows XP machine.
I unchecked the box to update the time from a time server (Internet time) and it's seem that this was what was causing itunes and its descendant to crash.
Now it seems it turned back to normal operation.
Please let me know if this fixes it for you as well.

Hey! apple mobile device helper keeps crashing!!!

Itunes keeps crashing due to the apple mobile device helper!!!! I have now tried absolutely EVERYTHING that apple suggests and nothing works it has resulted in me not being able to restore my iphone and i have no numbers, no nothing!!!
