MobileDeviceHelper Has Stopped Working (Win7x64 / iTunes v12.3.1)

Have you tried the reinstallation steps set out in the second box of Troubleshooting issues with iTunes for Windows updates yet?

I have the exact same error. Started at the end of September after I updated iTunes. I have done all of the above, plus running mobile device helper in compatibility mode to no avail. Resorted to wiping my computer and doing a clean install of Windows 7, Norton AV and iTunes v12.3.1 ONLY. Updated all drivers and DLL's. Did not load any other software that was present before or restore my data backup. After moving my iTunes library over as per Apple instructions, I still get this error. So much for getting the new iPhone 6S I really want, since I can't restore a back up of my current phone to it.

For general advice see Troubleshooting issues with iTunes for Windows updates.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach.

Review the other boxes and the list of support documents further down the page in case one of them applies.

The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.

Your library and device backups should be unaffected by these steps but there are links to backup and recovery advice should it be needed.

If the issue persists and you have a 64-bit system try the for older video cards version which is a 64-bit installer for mostly 32-bit code, similar to all 64-bit versions of iTunes up to 12.1.

Hello,

Thank you for your reply. I had tried most of these fixes already (google showed most of them). I finally gave up, formatting the laptop hard drive, restored from factory settings partition (its a Sony Vaio), then just patched Windows with all current updates, then updated all Sony hardware drivers, then installed Norton Internet Security, then iTunes.

Same problem. Any attempt to use an Apple Mobile Device while in iTunes causes the 'MobileDeviceHelper.exe has stopped working' error. Windows doesn't have a problem I can access all three of my Apple mobile devices (iPad 3, iPhone 6, and iPad 6) in Windows explorer but if I plug them up while iTunes is open, MobileDeviceHelper launches an it crashes. Oddly, I can usually finish a backup in iTunes anyway, but I can't Synch or Restore.

Any suggestions?

If you have a 64-bit system try iTunes for Windows (64-bit - for older video cards).

I tried that as well before I sent my last reply. no difference. I can still see my mobile devices in Windows Explorer but any attempt to access them

in iTunes cause the 'MobileDeviceHelper.exe has stopped' error.

I have exactly the same problem and have tried every step listed here, outside of re-formatting the HD. I even cleared out everything relating to Apple while in Safe Mode including everything from the registry ( a lot of search/research).
The steps worked fine after August's Win10 install but now... nothing, not even on my backup tablet.

I have the same problem and have gone thru all the steps listed in this thread (except reformatting the hard drive). Now on iTunes 12.4 and the problem persists. Oddly enough, the iPad or iPhone remains linked to iTunes and will sync/backup if I just ignore the message and continue in iTunes.

I guess this is just another symptom of the disarray in the iTunes development team. It seems like they should be abler to eliminate this problem.

if I seem bitter, it is because I am. Just get the problem fixed, or get a new set of developers. I don't care which.
