Antminer S2 doesn't run

[Sammy75]

I bought Antminer S2. But, it couldn't run.
I think there isn't cgminer in my machine, because "Cgminer Version" is blank and "Heardware Version" is x.x.x.x.
So, I couldn't enter pool information to "Miner Configuration".
I don't know how to install Cgminer in this machine.
Somebody, please tell me how to run this machine.
