Download the .zip and extracted the content on the proper machine (or use the version that is shipped with "Empyrion - Galactic Survival Dedicated Server". See folder "...\SteamLibrary\steamapps\common\Empyrion - Dedicated Server\DedicatedServer\EmpyrionAdminHelper").
Please allways stop the Server, then start the Tool and then start the server to apply the Update.
Emp Admin Helper Lite - Like Full version, but you need FTP + an open Telnet Port on your machine you are running Empyrion
Emp Admin Helper Full - You need a dedicated server where you can manage your steam / empyrion game. The best way to do that is via the preinstalled Remote Desktop in Windows. Make sure Emp Admin Helper Full is running on that machine where your Empyrion server is running. Some server hoster also implemented EAH.
