A problem that occurs on iTunes and Vista
When i was using iTunes, i found an error ”applemobiledevicehelper has stopped working”. After browsing for a while, i found out the solution. The solution is by opening the Windows explorer and browse to “C:\Program Files\Common Files\Apple\Mobile Device Support\bin” and then you have to delete all the files there. except two of them; but it doesnt matter. Now reopen your iTunes and it will works normal again.
I hope this article can helps….
