Forza Horizon 4 download is failing at 90%

These steps can help you, give it a try.
Check for updates on Windows Update, update everything including optional/additional updates.
1. Logout from Xbox app and Microsoft Store app
2. Look for the Xbox app and Microsoft Store app in the Windows menu, right-click, click app settings and then click terminate, restore and reset.
3. Clear the store cache type ''wsreset'' in the Windows bar, run as admin, and wait for the screen to close and open the store automatically.
4. Open the Microsoft Store app, click on the 3 dots in the upper right corner>downloads updates>get updates and update everything.
5. Restart your PC, log in to both apps and see if that solves the problem.

I tried all of those steps but sadly it didn't work, I observed the download process more carefully, and I noticed that this error appears exactly when the game finishes the download and starts installing. Thanks for the tip though!

On your hard drive, there is a folder called ''WpSystem'', take ownership of the folder and rename it to ''WpSystem.old'', save and try downloading the game again.

This worked, thanks a lot!

If it's not too much of a bother, do you know the reason was behind all this?

Again, much appreciated!

Thanks for the response, it seems to force me to download "Forza Horizon 4" first. When I click pause it's download and then try to start download on "Forza Horizon 4 Standard Edition" it stays at "Downloading" and starts Downloading process of "Forza Horizon 4". I also tried logging into my account on different computer which worked.
