Normally, if the main menu options in the Tekken 7 game are still grayed out it is due to the fact that the game has either:
- Not completed installing to the system
- Had an error during installation that prevented the game from installing correctly
In both instances, this can be fixed by either waiting for the game files to finish installing (for the first possibility) or uninstalling the game and then re-installing it (for the second possibility).
