Bought Forza Horizon 3 Ultimate Edition, but Car Pass won't install

The Ultimate Edition comes with:

- Forza Horizon 4

- Car Pass

- Best of Bond Car Pack

- VIP

- Formula Drift Car Pack

- Fortune Island

- and the Second Expansion, which hasn't been detailed yet. Just that it's supposed to release in the first half of 2019.

Here is a complete car list:

i can't find a listing for the Windows version, but the Xbox One listing says it's going to use Play Anywhere, so one purchase should work on both systems.

"The Car Pass brings you six monthly car packs (7 cars each) beginning in October 2016, ending March 2017. That’s 42 amazing new cars total."

hopefully that answers your question. let us know if you need more assistance.

Hey, guys! These are not sent as codes. They are provided as entitlements based on the purchase you make for Forza Horizon 3.

For the Ultimate Edition, you should have access to the
Car Pass and
All-Stars Pack. If you see that these are already purchased on the site, I suggest you do a search for their specific titles on the Xbox One console and download them directly from there.

For the Standard Edition, it should have come with the Rockstar pack and the Meguiar's Car Pack, but I am unable to find those online at this time. MrEldorado, can you please check your Manage Game section for Forza Horizon 3 to see if that content is there?
Thanks!

Forza Horizon 4 Ultimate Edition digital bundle includes early access, allowing you to play four days early beginning September 28, Car Pass, VIP Membership, Formula Drift Car Pack, Day One Car Pack, and two game expansions when they become available.

Hope this helps.
