so i got forza 4, go to install it to my hdd (as i do with all my games) but there's simply no option to install it. tried discs 1 and 2, i go to the home menu press x to browse games, and instead of having a play option and an install option, there's only a play option. and no it's not already installed. looked up a video (http://support.xbox.com/en-US/games/xbox-games/manage-game-library) and it clearly shows him installing forza 4, no problems. i did check with other games and i can install them. whats my deal here?
Are these retail discs or backups? If they are backups, have you run them through abgx360 to ensure they are valid?
Do you have enough space to install the game on your HDD?
