"The iPad "iPad" cannot be used because it requires a newer version of iTunes."

Hello Apple Communities! I hope someone has already solved this one. I just bought an iPad Pro, new from AT&T. Got it home and plugged it into my Windows 8.1 machine and got this message: "The iPad "iPad" cannot be used because it requires a newer version of iTunes." I am on the latest version of iTunes(64) I can find,12.1.3.6. and iOS is 9.3.2. I've seen a few people complain about this happening on a MAC or Windows Vista, but I haven't seen anyone with Windows 8.1 complaining. Any ideas?

I have uninstalled and reinstalled iTunes and Erased the iPad, though it was new already. Not sure where to go from here.
