[EN/FR] UE4 fatal error when launching the game

(I dont have the best english, excuse me for that, I hope it will be clear enough) Hello, my game has fatal error since I tried to download Halo 4. (Which I cancelled because I didnt have enough space)

I uninstalled it thrice now, verified MCC files via Steam, I tried the launching settings thing ( -WinX=0 -WinY=0 or smth like that?) aaand I think thats it.
It is not the first bug I have with MCC, since I bought it (since May) I dont get achievements at all. (Halo Reach, CE and 2 beaten in legendary, absolutely NO achievements. In the career option it says that i never played Reach, CE or 2)

I really hope this gets fixed/That I will fix it because i want to play Halo and especially playing for the very first time Halo 3 ODST.

Pour les français qui pourraient passer par là, et je l’espère, j’ai un problème depuis que j’ai essayé de télécharger Halo 4 avec Steam. Ce problème est le “Ue4 fatal error”, en gros Halo MCC crash dès que je le lance. J’ai essayé de désinstaller 3 fois, j’ai vérifié les fichiers de Halo MCC via Steam, j’ai changé les paramètres de lancement via Steam (-WinX=0 -WinY=0) et c’est tout. Ce n’est pas le premier bug que j’ai avec MCC, il y a aussi le bug des succès que je n’obtiens pas. (Finir Halo Reach en légendaire par exemple ben… j’ai pas les succès qui vont avec. Pareil pour les options où on voit nos succès in-game ça dit que je n’ai JAMAIS joué à aucun des 6 jeux.)

J’espère que vous pourrez m’aider/ que ce sera fixé. (problème qui a l’air plutôt répandu)

i can’t install MCC from game pass
there is a " loading error" for every drive i chose (all my drive have aver 250 go free) when i launch the instalation
the “loading error” says that my drive have not enough space on my drive…
i try a lot of fix to correct and nothing change
for the history MCC was install on my drive and work, i have to uninstall the game, and now i try to re install and it doesn’t work
je suis fançais aussi

thanks for any tips to solve this stupid problem

If you have a NVIDIA card you can use Geforce Experience (part of the driver package) to force the game to start in windowed mode. I used this to get past the FATAL ERROR! message.

Si tu utilises NVIDIA, essaye d’aller dans le panel où tu peux optimiser tes jeux, va sur Halo MCC, clique sur “paramètres personnalisées” et tu mets en fenêtré avec ta résolution d’écran et ça marchera normalement
