Downloading on wrong driver, help. Platform: PC

When I pre-ordered FH4 I wasn’t able to choose which driver to install the game on. Therefore it decided for me - my main C drive… which does not have enough space. My D drive does though. How am I able to switch drivers at this point?

I believe on Win 10 go to: Settings>System>Storage then find “more storage settings” then “change where new content is saved”

When I did it, it gave me an option to choose between my 2 drives, so I don’t know.

As said go to Settings/Apps/ Click on Forza horizon 4 then a ‘move’ button displays. Click move and move to desired drive.
