I am going crazy trying to get my pc, Dell XPS One (vista) to update to iTunes 10.5 so I can update my iPad 1 to ios5! This is the computer it is synced to. First the update failed several times, then on another forum it was suggested to turn off antivirus (I have the free Avast). I did that and still failed. Next it was suggested to uninstall the antivirus, did that still failed.
I have a brand spanking new MacBook Pro and was going to switch the iPad to that but thought to get the update done on the pc first. I also have a laptop Dell Vostro (XP) both of these computers updated to iTunes 10.5 with no problem.
I tried hooking up the iPad to the mac, did a sync and now everything that is on the iPad appears to be in that iTunes. Not everything from the pc iTunes is on the iPad, I have several TV shows and some music not on the iPad. But I can't upgrade there as that is not where I purchased the apps etc.
The next suggestion was to uninstall iTunes and reinstall. First I backed up the iTunes media file to an external hard drive (seagate goflex that is supposed to be mac compatible) I followed the directions on the apple site to uninstall and reinstall iTunes, but have had nothing but trouble.
I get all sorts of errors, first it says CoreFoundation.dll was not found and reinstalling the application may fix. So I try to reinstall then "encounters errors, reinstall" install again, get 0x80070002 error and while I was googling that I get a message iTunes is installed!! Yay?? No joy, as soon as I click finish I get error that Apple Application Support is required, uninstall and reinstall......yet again all the above happens: the uninstall of everything, run ccleaner, restart install and this time the end result is that "Apple Mobile Device failed to start. Verify you have privileges...."
I did it all over once again and this time the end result was iTunes installed but again Apple Application support was not found...... Gahhhh!
Is there any way I can move the saved iTunes media file from the xhd to the mac and then update the iPad there???? I am not technical at all and my head is spinning at this point. I've spent 3 days trying to get iTunes updated to no avail...... What if my pc had exploded and wasn't even there any more? How would I sync and backup my iPad then??? I am about ready to blow it up!
