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 must be installed:

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

The instructions below apply for the .exe installation only. Zip/OvGME/JSGME installation is described inside the README in the downloaded package.

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:

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).

Be careful, DCS port and LotAtc port must be different

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. You can use this checklist


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.
