More Activations?

[Frosties]

My brother bought DCS:BS and tried to install.

He installed the game, and then tried to start it.

They asked for the serial and he entered it, but then he couldnt read the "buttons" to move forward.

 

And while trying finally the text says all of the activations are depleted!

 

How to obain more?

 

Is there a guide on how to proceed thru the installation?

A guide that explains wich button to press when?
