There is no dlc after instaling

Multiplayer Instructions from the GOG Vers. maybe it helps here also:

If you want to host a game:

• By default the game uses the port 7777, so make sure this port is properly
  forwarded on your network router and not blocked by your firewall
• Launch Planet Crafter, then create or load a game
• Provide your public IP address to other players (or your local LAN IP if other
  players are using the same network)

If you want to configure the port and your in-game name:

• Create a file named "Server.conf" in the folder
  %appdata%..\LocalLow\MijuGames\Planet Crafter
• Copy the following line inside this new file:
  {"hostPort":7777,"hostPlayerName":"Convict-1"}
• Configure the "hostPort" and "hostPlayerName" variables with the values you
  want to use
• Make sure the port you've set is properly forwarded on your network router and
  not blocked by your firewall

If you want to join a game:

• Launch Planet Crafter
• Click on the "Join" main menu button
• Enter the name you want to use and the address of the server you want to join
  with the format "ip_address:port" (ie: 127.0.0.1:7777)
• Click "Join"

There is full English support via the English interface, English audio and English subtitles!
