How to find your serial number within Steam
Posted by on 16 February 2012 11:21 AM

Select the game from your Library. There is a CD-Key link on the right-hand side that will show the serial number.

You can click that and you will see the following window.

The key is in a format something like this


(30 characters long)

Always select the Copy Key to Clipboard option when copying the key into the Stardock Registration prompt, just to avoid any human error.

Click 'COPY KEY TO CLIPBOARD' and then paste this into the activation dialog.

If your view does not look like that, alternately, you can right click on the game from within your library and choose 'View CD key' or you can hit the option depicted here.
