Install Space Engineers. - Launch a command prompt and navigate to where you installed steamcmd cd \steamcmd - Run steam command steamcmd - (optional) If you want to install the application in a different location use the force_install_dir command force_install_dir c:\se - Authenticate to steam to authorize your download login <steam username> <password> - Update / Install the app app_update 244850 You'll see the program downloaded and installed. You can toss this in a script for a quick update. You can also do this in a single line via the CLI or script, ie: steamcmd +login <username> <password> +force_install_dir d:\SE\ +app_update 244850 +quit A few things: - You may need to log out of steam on another PC, I have had some issues when logged in on both. - It will cache your password, so you do not need to specify it every time or save it in the script.
