Before you try searching the Windows Store to buy/install the game, please make sure you have updated your Windows 10 to the current build and have the most current driver for your video card and PC hardware. Making sure you are fully updated, and rebooting, will solve most problems without the need for a new troubleshooting thread.
NVIDIA and AMD released FH3-ready drivers on September 21, 2016 in advance of FH3's Ultimate Edition release. This post may not be updated as frequently as the official sites! Always check for the most recent driver builds and their release notes.

Windows Version
Commonly reported Issues:
- FH3 not found in the Windows Store
- Found but Not Available
- Error codes
- Can't set installation drive
Solution: The most likely culprit is your version of Windows operating system. (You should run these steps even if you think you're up to date.)
Find your current Windows version
On your PC, click the Cortana circle and type dxdiag or winver to see your current Windows version and build number. If you are on version 1511, you need to update.
Update your Windows version
In your PC Settings > Updates & Security you may see "Your device is up to date" even if you don't have the Anniversary Update installed. Click the "Learn more" link to load the support page and then click "Get the Anniversary Update now" to install it.
Reboot and run dxdiag or winver again and confirm that your version numbers match the most recent build of Windows 10.
Note that even if you have the most recent version of Windows, the Store may not allow you to buy or download the game due to minimum computer hardware requirements. Don't try to debate this - minimum requirement means minimum requirement. If you think your hardware is sufficient and you're still having trouble with the Store, try clearing your cache by running WSRESET from Cortana.
Windows Store direct links
To buy for PC play you don't need to own a console, and you can buy through the Xbox App on PC, or Windows Store app, or direct windows store links.
FH3 - Manage Game
- Full game pre-loading became available on September 20 - You can confirm installation on your PC by typing Apps & Features in Cortana.
- The Car Pass may show as Not Available to pre-load, which is fine because you can't use it until October.
- You can confirm your purchase in your Microsoft Billing History: https://account.microsoft.com/billing/orders#/
Are you a Play Anywhere user? Update your console too.
Having the most recent Windows version will enable the most current features in the Xbox App for Windows and ensure that your console and PC get along well for streaming, Game Bar, etc. On your console go to Settings > System and see if there are any available Updates to install. Xbox Preview members in particular may see multiple updates in a given week, and experience trouble connecting online if an update has been issued but has not yet been installed.
