Apple Mobile Device Support won't install, keeps rolling back..

After a couple days searching the internet for a solution I pieced togetherwhat my problem was from several forums and fixed it; maybe my solution/problemis similar to all of yours. (NOTE: I’m running Windows XP Professional, 32-bit,with Service Pack 3 – so you’ll have to translate my issue into your Windows 7format because I have no idea how to operate things is that version of Windows.)

I traced the error to the Apple Mobile Device USB Driver under"Universal Serial Bus Controllers" as others have too (everything inthe iTunes installation would install perfectly well except for Apple MobileDevice Support). However, my problem wasn't with the driver itself -- I had amissing .dll file on my computer for the Hardware Update Wizard (whenever Iwould 'right click’ any USB driver and select "Update", HardwareUpdate Wizard would not open; nothing would happen).

So, I went searching for this problem next, and I found this website: http://kf.livejournal.com/208963.html?view=2699587#t2699587

The page suggests that the problem is a missing .dll file called “newdev.dll”that should be located in “C:\WINDOWS\system32\” (again, I don’t know theequivalent folder for Windows 7, so someone else will need to find out where “newdev.dll”belongs) – I did a search of the .dll file on my computer and found it missing.However, I found another copy of it on my computer using “Seach Everything” (foundhere: http://download.cnet.com/Everything/3000-2379_4-10890746.html)– but, you can also use the Windows Search tool. There were copies located in “C:\Windows\system32\dllcache”and “C:\Windows\ServicePackFiles\i386”. (I would suggest searching for itrather than locating it manually in Explorer in case its in a hidden folder.)

I copied one of the preexisting files of “newdev.dll” and pasted it into “C:\WINDOWS\system32\”.Then I tried re-installing Apple Mobile Device Support and it worked (norolling back installation). When I plugged my iPhone back into my USB “AppleMobile Device USB Driver” reappeared under “Universal Serial Bus controllers”in “Computer Management” – all I had to do was “Enable” it again and I hadaccess to my iPhone in iTunes again.

Also, I had copied a preexisting file of AppleMobileDeviceSupport.msi to mydesktop prior to uninstalling everything, so when I tried to reinstall iTunesand Apple Mobile Device Support failed to install all I had to do later when Ifound the solution was reinstall AMDS. If you do not have a copy of “AppleMobileDeviceSupport.msi”try completely uninstalling everything (like so many other forums suggest, asdoes Apple, here: http://support.apple.com/kb/HT1925),and reinstall iTunes with the Hardware Update Wizard .dll file replaced. (I can’tsay if this entire reinstallation will work since I only had to install AMDS.)

Hope my problem was your problem as well.

Hi, I too am having this same issue... I have Windows 7 64 bit and after updating to iTunes 10.2.2 - I no longer have the software Apple Mobile Device support and itunes won't detect our iphones and ipad. I am not really comfortable doing what is being suggested here as I'm not very technically inclined. But the last suggest from topher.sgordon makes sense to me as I got an error message APAgent.exe - system error " The program can't start because dnssd.dll is missing from your computer. Try reinstalling the program to fix this program."

If anyone can translate the above recommendations for use with Windows 7 (and in terms that I could follow) it would be really appreciated.

Thanks

Hey guys, I've been having the same issue as described in this post and have just found a way to resolve it.

I'm running Windows 7 Ultimate 64 bit and the AMDS Installer kept rolling back. I tried most of the things described in this post and finally came to a conclusion. I noticed that my other computer running Windows Vista 64 bit had the application installed without any issues, as you have probably already found out, the AMDS Installer file cannot be run in compatibility mode, however the iTunes64Setup.exe file can. These are the steps that I used to fix the issue:

1. Click Start and open the control panel, from the list select "Programs" and then select "Uninstall a program"

2. Uninstall the following applications: iTunes, QuickTime, Apple Software Update, Apple Application Support and Bonjour.

3. Restart your computer.

4. Locate your iTunes64Setup.exe file or download a new one from the Apple website.

5. Right-click the iTunes64Setup.exe file and select "Properties" from the bottom of the list.

6. In the properties window, select the compatibility tab.

7. Check the box that reads "Run this program in compatibility mode for:" then from the dropdown list select "Windows Vista"

8. Check the box that reads "Run this program as an administrator"

9. Click Apply and then OK.

10. Run the iTunes64Setup.exe file and follow the installation wizard as usual.

I am having the same issue. We have a new computer, new Nano 16g. I Tunes will not download the device manager module. I have spent 20 hours between Apple, Dell and Norton trying to isolate the problem. Apple is still researching what is wrong. I have exchanged Nano's 3x but the problem is with the download.

I'm running Windows 7 Professional, brand new computer, everything. I get the rollback and Apple didn't know what that was about. I"d like to move forward.....

Have you tried following the steps that I've posted?

I've suffered through every update with the same issues but have to say Alex - the one you provided seems to have solved my problems as well.

Thanks
