Once GOG Galaxy has installed, open the application and you should be met with a Login window.
Step 2: Login or Create an Account
You only need to have one GOG account – if you already have one then simply login to your account using your username/password.
If you do not have a GOG account then go the link that says “Sign In” on the main GOG website – where you downloaded GOG Galaxy from – and then click on “Create Account”.
You will need to activate your email account by click a link sent to your email address from GOG.
Step 3: Activate Your Game
Be sure that you are logged in to your GOG account and go to: https://www.gog.com/redeem

Step 4: Download Your Game
Once your code has been redeemed your game will appear in your Library on both GOG.com and through GOG Galaxy.
Some games can be installed directly from your browser, while others will need to be downloaded through GOG Galaxy. Installing through GOG Galaxy allows for the application to automatically download updates for any games that you have installed.
Once a game has been downloaded it should be ready for you to play!
