Updating to iOS 10 with Windows XP
I have an older PC with Windows XP, Media Center, SP3 (cannot afford to update or buy a new PC...on disability 8+ yrs). It has iTunes 12.1.3.6 installed. Every time I try to update my iPad or iPhone to iOS 10, iTunes indicates that I need iTunes v12.1.2 and offers me a button to download it, but when I click it, nothing happens.
Where can I download this version of iTunes for Windows XP?
iPhone 6s, Windows XP, iTunes 12.1.2; iPad
