One of the problems you may encounter when trying to run a game via Steam is the “Game failed to start (application already running)” error message. This problem occurs if the previous game was not stopped properly or if you simply forgot to stop it. Sometimes, however, this problem can be more difficult to solve, especially if you permanently shut down the game after exiting it.
