Can't seem to reinstall Forza Horizon 4 after reinstalling Windows.

apart from reinstalling Windows.

Hello Jack,

It might be worth adding, that I have the exact same issue as you do, with Forza Horizon 4 Demo and Forza Motorsport 7 trial (Forza Horizon 3 Demo works fine though), and in my case reinstalling Windows did not help at all. So it's probably not worth trying.

I finally got Forza Horizon 3 downloading on my PC, but I had to reinstall Windows to get it to download.

If you can't see an install link under Forza Horizon 3, when you click to it through the Ultimate Bundle, then your install of Windows 10 might be "broken". Performing a reset might help resolve the issue, but it is time consuming, and will require the reinstall
of some of your programs (the Windows 10 apps, however, 'should' be reinstalled)
