Enabling Steam Update from the browser ( TCAdmin v1.0.4574.34935 or greater is required)
1 - Go to the game's settings. In the "Steam Game Type/App Id" field set the game's steam app id. Enable for admins and/or users. A list of supported servers can be found here: https://developer.valvesoftware.com/wiki/SteamCMD#Supported_Servers
2 - Go to the System Settings > Steam Update Settings. Enter the steam account and password used to log in to steam. It is recommended that you set the user to "anonymous" and leave the password blank. If the user and password are left blank the Steam Update will ask the user to enter his steam user and password.
3 - Create the folder TCAdmin Control Panel\Monitor\SteamCmd. Download steamcmd.zip and extract to that folder. Run steamcmd.exe once so it updates itself.
