So, go ahead. Purchase your key from a trusted retailer. Activate it on Steam. Load up the European or American map. Start your engine. And remember: In construction, as in gaming, a solid foundation (and a legitimate license) is the only thing that holds up.
A: If you registered it on Steam previously, log into Steam and use the "CD Keys" method above. If you never activated it, contact astragon Support with a photo of the physical disc and proof of purchase. Replacement is not guaranteed.
Launch the Steam client on your PC. Step 2: In the bottom-left corner, click "Add a Game" (or "Games" in the top menu > "Activate a Product on Steam"). Step 3: Click "Next" and then "I Agree" to the Steam Subscriber Agreement. Step 4: Enter your Construction Simulator Activation Key exactly as it appears. (Note: Dashes are automatically added by Steam, so you can type them or let Steam insert them). Step 5: Click "Next." If the key is valid, the game will be permanently added to your library. Step 6: Click "Install" to download the 15-30 GB of construction goodness.
