MobileDeviceHelper has stopped working - and will not stop stop-working!
Hello.
First off, let me state that at one time iTunes and the syncing of my iPhone and iPod Touch worked great on my laptop (an HP dv5t running 64bit Win Vista). Two months ago when Apple updated iTunes from version 9.0.3 to 9.1 there seemed to be many people who encountered errors (syncing issues). Me included. I decided to wait and see what solutions might pop up - either in forums or in the form of an update from Apple. Soon Apple released 9.1.1. Unfortunately, the update did not fix my issues and I am still unable to use iTunes on my laptop.
Here is what is happening:
iTunes alone works fine. I can open it, play music, see my apps, etc.
As soon as my iPhone (or iPod) is connected to the laptop I get persistent messages that "MobileDeviceHelper has stopped working" as well as "iTunes was unable to load dataclass information from Sync Services." These messages cause the iTunes application to lockup and the only way to stop them from appearing is to unplug the iPhone from the computer.
I have tried 'repairing' iTunes, deleting the iTunes preferences files as suggested on Apple's main support page, reinstalling, reverting to previous version of iTunes, doing so with great care to remove any remnants of former installs. I have also attempted some of the .dll fixes as suggested by earlier posts (moving around libxml.dll, or similar files, from the windows directory and seeing if anything changes). No luck.
If there has been a fix for this then I apologize for this post, but I have not seen any 'solution' that works for me. Any help would be greatly appreciated.
