I got the retail version of Space Engineers (Limited Edition) and put it into my computer. The instruction sheet that came with the game says that when I open the menu there should be some installation instructions. The only options that came up were "Redeem Steam Key", "Install Miner Wars", "Artwork" and "Soundtrack". I have redeemed the steam key, but there is no option to install it. Is there a way to do it from the disc, or do I have to download it?
EDIT: I have tried both ways of installing from disc (Using the "Run [Windows Function]" feature and the "Restore From Disc [Steam Function]") but both do not work. Trying to do it with "Run" just opens steam, does nothing else. But using "Restore", I cannot do it as it says there is no back-up. Is Space Engineers a game that HAS to be downloaded?
Best Answer
After you activated the key, just open your Steam library and download the game. It's only about 1.5 gigabytes, and this will be the cleanest and simplest way, since the only important part of your retail copy is the key it included, which you said you redeemed.
