I bought the Skyrim Legendary edition and it came with a steam code. Where do I enter this Steam code?
When logged into Steam, go to the top bar, click on on the small word "Games" (above Store and Library). In the drop down menu click on "Activate a Product on Steam...". On the pop up that appears, click on the "next" button on the bottom. After That click on the "I agree" button. Then enter in your Steam code into the text box that appears.
Easier to activate through the website than through the app.
