Get it

The server is free and only available for DCS World 64bits (this is because ED has stopped supporting the 32bits version of DCS World). You can get LotAtc 4 DCS server from here: Download.

Installation

Installing as a DCS module

LotAtc server is a module for DCS World. It needs to be installed “within” DCS World. This is mandatory for the LotAtc server to be able to run. LotAtc server may be installed:

  • in the Saved Games directory, along with your DCS personnal files/settings if you use the .exe installer or
  • in the simulator installation directory if you use JSGME.

The instructions below apply for the .exe installation only. JSGME installation will be described later (documentation = WIP)

The installation is automatic, simply run the installer (Setup_LotAtc_4_DCS_Server_xxxxx_64bits.exe with xxxxx being the version number) and check that it finds & targets the correct installation folder:

Default folder is C:\Users\%USERNAME%\Saved Games\DCS

You’ll get a pop-up “Folder exists”, please confirm that yes, you would like to install to that folder anyway:

Only for the 1.0.2, for 1.0.3, the following part is useless

The installer will also put one sub-folder and 7 files into your DCS World\bin folder. It will locate this folder through your Windows’registry via the value of the “Path” key in HKEY_CURRENT_USER\Software\Eagle Dynamics\DCS World. The folder and files are then automatically copied into the correct folder, and you should not care about them.

The relevant elements are:

  • one sub-folder named ‘plugins’
  • 3 DLLs files: Qt5Core.dll, Qt5Network.dll and Qt5Sql.dll
  • the qt.conf file

If, for whatever reason, the installer is unable to read the registry key, or unable to write the files into the target folder \DCS World\bin, it will put them into \Saved Games\DCS\bin, for you to move them manually.

So if, after installing LotAtc 4 DCS server, you have anything else than the vcredist_x64.exe into your \Saved Games\DCS\bin (as shown on the image below) then you have to move those elements (the ‘plugins’ folder + 3 DLLs + qt.conf, not the vcredist_x64.exe) into the “bin” folder of your DCS World installation:

If those files (‘plugins’ folder + 3 DLLs + qt.conf) are not present into the intended DCS World\bin folder, DCS multiplayer will act weird (no login/pass for master server, no connexion speed choice… glitches… crashes… and so on). Keep smiling: Putting those files (‘plugins’ folder + 3 DLLs + qt.conf) into the intended folder +solves everything+, without any sequelae!

Granting Network access

Being a server application, LotAtc 4 DCS server must be able to “listen” for incoming clients on its communication port. The protocol used is TCP and the default port is 10310.

If needed, you may change the port number, but not the protocol. Don’t forget to inform your clients who will need this information to connect to your server.

Regarding your firewall configuration: as a module, LotAtc 4 DCS server acts as a part of DCS World. Hence you have to allow DCS World (dcs.exe) to communicate through the TCP 10310 port (or your personnalised port number).

If you have a router (or an internet box with a router feature), you must configure it to relay the incoming TCP 10310 communications to your PC identified by its Local Area Network IP. This is called Port Forwarding (or sometimes NAT). Refer to your router/box user manual for how to do that.

By the way, you already did that for your DCS server: it’s the same operation, just a different port number (DCS World uses TCP 10308 & UDP 10308, whereas LotAtc 4 DCS uses TCP 10310).

What’s next?

After installation succeeds, the LotAtc 4 DCS server icon will be displayed on your DCS splash screen, along with other DCS modules:

Once you get this, please follow the Server user manual instructions to enable & run LotAtc server within DCS World.

Uninstallation

Run the uninstaller via the start menu shortcut.

If you don’t have a start menu shortcut, use windows add/delete programs feature, or execute the uninstaller directly from your C:\Users\%USERNAME%\Saved Games\DCS folder.
