Voilà la solution pour tous ceux qui ont un jeu qui crash après la scène d'intro. Le problème vient en fait de Windows Media Player qui a besoin d'être installé. Enfin pas tout à fait, mais plutôt de 2 fichiers DLL que WMP utilise. Voici donc la solution, tiré de ce forum:

1) Install WMP for the last time
2) Copy wmp.dll and wmploc.dll files that are located in your Windows\SysWOW64 directory (or System32 for 32-bit Windows) in a safe place
3) Uninstall WMP for the last time
4) Copy your backup wmp.dll and wmploc.dll in their original location (Windows\SysWOW64 or System32)
5) In your SysWOW64 or System32 folder, hold Shift, right-click in it and select "Open command window here"
6) Register the DLLs by entering the following command: regsvr32 wmp.dll (it is not necessary to register wmploc.dll)
7) You should have an alert saying that the operation was successful
