The game is not running on my pc.
That's all well and good, but if you want that to change, I'm afraid you're gonna have to give a lot more information about what exactly is going wrong, such as what behavior the game/application is exhibiting.
Is it giving an error message? (And if so, tell us what it says.) Is it simply showing a black screen on launch? If you're able to get to the main menu, what steps are you taking that causes it to crash? Etc etc... That kind of stuff.
