I have a lot of trouble sync my iphone 4, Ipad 1 and various ipod since 2 month.
Every time I try to sync them, I get an error message : appver: 17.1008.10.20 or szAppVer: 18.104.22.168.
I will also get the following from time to time : unknown error (-50), unable to sync
It is simply impossible to back-up my devices.
I have tried the following:
uninstall everyting apple (itune, safari, quicktime...) and do a clean install.
restore my devices to factory default
try to use the autoruns.exe
Aside from that, everyting is working fine. The apple store is working fine (not the blank apple store situation). Icloud is desactivated.
I am now out of ideas.
My system : XP
I am also running an Apple TV
Anyone to help me ?
ps sorry for the poor english !
Given that you're on XP, we'd better try the following document:
