The regular installer from the i Tunes website will not work.
You may need to remove any lingering components and start fresh if you're having problems.
You'll need to use a special installer from Apple for an older version.
This version of i Tunes will allow you to connect to i OS 9 devices.
So the latest versions of i Tunes and of i OS for your i Devices won’t work on Windows XP or Windows Vista.Be mindful that any restores of i OS10 require i Tunes 18.104.22.168 and consequently, need a newer Windows OS.If you go this route, you need to restore via i Cloud or move your i Tunes 22.214.171.124 backup to a computer with a newer windows operating system (7 and beyond.) Further bad news is that i Phones and i Devices running i OS 10.2 and higher require at least Windows 7 or above.We’re sorry; we know a lot of your like XP or Vista for security and many other reasons.Sadly at this point there isn’t much to do other than upgrade your Windows OS.
