Cant install Forza 7

this has been an absolute nightmare. i bought the ultimate edition for windows 10 and have been trying to download it since tuesday. i have downloaded it 5 times now, by the end of each download it just resets or gives me an error code. it tells me each time its installed, but it keeps download more and more data, to the point where the download size says it was 198GB instead of the 95 or so. i dont even know where any of that data went, its not on the hard drive i told it to install to. i dont get it at all. so i think ok maybe the preload is bugged or whatever, ill just wait. then comes midnight, the game becomes available to play. i start the game up and it tells me its checking windows version (updated fully) and then says it cant connect to forzas servers. i cant even launch the game, it just tells me to try again. so i try again, same thing. 11 hours later i am writing this and i still cannot play the game i installed ,at this point, 4 times. i decide to redownload it and at about 72GB the download fails becuase of server issues, [Mod Edit - Abbreviated profanity, profanity and profanity that is disguised but still alludes to the words are not permitted - D]. here i am at 11 AM trying again to get this working. i go to the windows store and it tells me to hit play, i hit play and same thing. but now it tells me there an update to download, i click update and the update size it 95GB, which means i am now downloading a nearly 100GB file for the SIXTH TIME this week. it tells me the game is installed, and i can launch the app but i cannot actually play the game, or get to the menus or anything. my data usage is just shy of 500GB this month now and i am very mad. if this 6th download doesnt work then i am out of options here, i literally dont know what to do to fix this. this has been absolutely ridiculous.

What is the error code? that “oversized” download thing happened before in the days of FH3, i can’t remember the solution to that.
Maybe just try a clean reinstall of Windows10?
