Wine /home/(username)/Downloads/SteamSetup.exe export WINEPREFIX=/home/(username)/.wine-steam Optional: set WINEPREFIX to a special path if you want to isolate Steam from other wine apps you run. Next, run Windows steam using wine (I'm assuming you have wine installed from your comments). go here and click the 'Windows' link right below the install button. From the Steam website, you can download the Windows version of steam.
