My iPod touch was working well with my laptop untill the laptop crashed. The laptop runs windows 7 and i used a recovery disk to get the machine working again. I updated windows from the microsoft site which included service pack 1.

I have read the support documents from Apple, and other postings on this forum. Despite following all the advice the problem is still not resolved.

The fundamental problem is that the current version of iTunes is not installing the Apple Mobile Device Support. I have followed the steps in how to uninstall iTunes in the correct sequence. I have removed all traces of iTunes, iPod, Qucktime and Bonjour. I have searched through the hard disk painstakingly to ensure all Apple files are removed. I cleared the recycle bin, shutdown my firewall and virus protection. The laptop was restarted cleanly, I then downloaded the latest version of iTunes. I ran the installation as Administrator.
The installation failed to install the Common\Apple\Mobile Device Support folder with the required files.

I tried again several times. I then uninstalled all the apple software and followed this by using Regedit to remove all entries relating to iTunes, Bonjour, Quicktime, Mobile Device Support etc. I then downloaded the iTunes installation file again. Running the install produces the same problem, Common\Apple\Mobile Device Support is not installed.

I have spent 2 days trying to resolve this issue for my daughter, and the level of frustration i feel with regard to Apple is extremely high. Can anyone suggest further steps to try, or is just far simpler to junk the ipods and get generic mp3 players

HP, Windows 7, with service pack 1

    After a couple days searching the internet for a solution I pieced together what my problem  was from several forums and fixed it; maybe my problem/solution is similar to 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 7 format because I have no idea how to operate things  in that version of Windows.)

     

    I traced the error to the Apple Mobile Device USB Driver under "Universal Serial Bus  Controllers". As other forum subscribers have found, everything in the iTunes installation  would install perfectly well except for Apple Mobile Device Support, which would "roll  back" and fail its installation. However, my problem wasn't with the driver itself -- I had  a missing .dll file on my computer for the Hardware Update Wizard that prevented me from  updating my drivers and installing Apple's Mobile Device USB driver.

     

    To test to see if your problem matches mine, 'right click' "My Computer"; 'click' "Manage";  in "System Tools" select "Device Manager"; open "Universal Serial Bus controllers";'right  click’ any USB driver and select "Update". If Hardware Update Wizard does not open -  nothing happens - then your problem is similar to mine. (However, if Hardware Update Wizard  opens perfectly fine for you, then your solution may be much simpler: several forums found  that uninstalling the Apple  Mobile Device USB Driver in "Universal Serial Bus controllers"  along with iTunes, Bonjour, Quicktime, Mobile Device Support, etc., then reinstalling  everything iTunes, and then re-enabling the new Apple USB Driver fixed the problem.)

     

    But, if Hardware Update Wizard fails to open for you as well, then this is how I fixed my  iTunes problem in conjunction with the Hardware Update Wizard issue:

     

    NOTE: I copied a preexisting file of AppleMobileDeviceSupport.msi to my desktop prior to  uninstalling everything, so when I tried to reinstall iTunes and Apple Mobile Device  Support failed to install all I had to do later when I found the solution was reinstall  AMDS from the .msi file. If you do not have a copy of “AppleMobileDeviceSupport.msi” then  just completely uninstall everything - like so many other forums suggest - and you can  reinstall everything at the end of these steps, hopefully with AMDS if this works for you.

     

     

    1. Uninstall everything related to iTunes if you haven't done so yet. (For complete  uninstall, see: http://support.apple.com/kb/HT1925)

     

    2.Uninstall the Apple Mobile Device USB Driver: 'right click' "My Computer"; 'click'  "Manage"; in "System Tools" select "Device Manager"; open "Universal Serial Bus  controllers"; locate "Apple Mobile Device USB Driver"; 'right click' it and select  "Uninstall".

     

    3. Next, you need to find the missing .dll associated with Hardware Update Wizard: The  missing .dll file is called “newdev.dll” that should be located in “C:\WINDOWS\system32\”  for Hardware Update Wizard to work. (Again, I don’t know the equivalent folder for Windows  7, so you will need to find out where “newdev.dll” belongs.)

     

    I did a search of the .dll file on my computer and found it missing in "system32". However,  I found another copy of it on my computer using “Search Everything” (found here:  http://download.cnet.com/Everything/3000-2379_4-10890746.html)– but, you can also use the  Windows Search tool to find other copies. There were copies located in  “C:\Windows\system32\dllcache” and “C:\Windows\ServicePackFiles\i386”. (I would suggest  searching for it rather than locating it manually in Explorer in case it’s in a hidden  folder.)

     

    If you can find no copy of "newdev.dll" on your computer then you'll need to find it either  on your Windows installation CD or online. Since I already had a copy of it I can't tell  you where else to locate it.

     

    4. Copy the preexisting file of "newdev.dll" and paste it into "“C:\WINDOWS\system32\” (or  where ever else this .dll file belongs on Windows 7).

     

    5. Reinstall AMDS from AppleMobileDeviceSupport.msi or, if you do not have this .msi file,  completely reinstall iTunes. Hopefully Apple Mobile Device Support should install this  time.

     

    6. Plug your Apple Device (iPod Touch, iPhone, iPad) into a USB port. Your computer should  recognize that the device has been connected.

     

    7. Go back to your USB Drivers under "Computer Management" (refer to step 2 above) and  locate the newly reinstalled "Apple Mobile Device USB Driver". If it has a red X over the  symbol for the device, 'right click' it and select "Enable".

     

    Your Apple Device should now be recognized in iTunes.

     

     

    Hope my problem was your problem and this process works for you.
