AMDS wont install. I have gone through all the proper steps to uninstall all apple software and then reinstall it. I am running windows 7 64-bit.Itune worked properly and synced to my old iPhone 4 no problem, but when I got the new iPhone 4s and updated iTunes, I couldnt get any device to sync or even show up in iTunes. iTunes keeps telling me to uninstall and then reinstall iTunes for windows 7 64-bit. Anyone else have this problem or know how to fix it?
