I plug in my new phone to to iTunes to sync pics and text tones etc and yet another update pops up. I go to install and after it downloads and starts to install I get an error. Restart laptop still does it. I download only and try to manually install then it says I need windows 7 Service Pack 1 64 bit. I have Windows 7 home edition 64 bit which meets the requirements acccording to Apple’s site. Smh. Pain in the a$$. Last night when I backed my iPhone 6 up and wiped it and restored to unlock it everything went smooth (even though I’m not sure it’s unlocked).
