This game requires Steam to download install and play.
Once you bought it from Gamersgate do the following:
1. Log in to Gamersgate (assuming you are not already).
2. Go to My Games section, http://www.gamersgate.com/account/games,
3. There you will find the list of games you bought, if you never activated your games, Magicka should display a red button that says: Show serial code. When you click on it, you will be able to see your serial code.
4. Once you have your serial code, you have to download Steam, install it and enter your serial code there.
The link to download Steam is: http://cdn.steampowered.com/download/SteamInstall.msi
Let me know if you could fix it please.
