Halo Wars 2 not allowing me to download it to PC

I recently bought a halo wars 2 ultimate edition code from a friend and redeemed it. But it will not allow me to download it to my PC it just says “see available on below for devices this product runs on. It won’t run on this one”. After contacting Microsoft and Xbox support they told me to come here and that you guys will be able to help. They gave me this reference number 1426840263.
Thanks.

Me and my buddy just paid for 2 complete editions and he is having the exact problem your having. He’s calling right now for a refund
