First Control Prefab is not working when i click on play.

i have added the first control prefab on a simple cube and it does not do anything when i play the game and i have removed the default camera as the prefab has its own camera. I am new to Unity. And under my Standard Assets, there is no Character controllers as i saw in many forums to check that and there is no CharacterMotor script also.

Try reinstalling Unity and creating a new project. The same problem happened to me and I fixed it with this.
