Installation

Installing the application

Note you don’t need DCS World or any module to execute the LotAtc client, it’s a stand-alone software !

After downloading the 64 bits installer, execute the “Setup_LotAtc4DCS_xxx_xxbits.exe” and follow the installation wizard.

During this step, you have to accept the end-user licence agreement and choose a destination folder for the installation of LotAtc 4 DCS.

Default path is C:\Program Files\LotAtc 4 DCS

LotAtc 4 DCS client will need:

  • about 340MB of disk space for the client software itself, and
  • an additionnal 330MB of disk space for the Relief database (terrain mesh, shared between LotAtc 4 DCS server and LotAtc 4 DCS client) put into {UserHome}\LotAtc 4 DCS\Data\ folder.

Regarding the Relief database in your LotAtc 4 DCS client, LotAtc installer will ask you if you want to download & install it:

  • If you already have installed LotAtc 4 DCS server (or intent to install it), you +don’t need+ to download & install the Relief database through the client installer: the database is mandatory for the server, and is included in its installer. Untick the checkbox.
  • If you have not installed LotAtc 4 DCS server (and don’t intent to install it), you may choose:
    • to take the Relief database, and get the elevation data of the mouse cursor point: tick the checkbox,
    • or not to take it, and have elevation indicated as zero anywhere on the map: untick the checkbox.

Network authorization

LotAtc 4 DCS client communicates with LotAtc server through the (default) TCP 10310 port. Ensure to allow LotAtc 4 DCS client to use that port to reach the server. Refer to your firewall documentation for how to do that. Most firewalls will ask permission on the first launch.

Being a client-only application, LotAtc 4 DCS client doesn’t need port forwarding (NAT) through your router. Only servers need to do that.

First launch, Demo mode & Licence key

On first launch, LotAtc 4 DCS client will display a “Not Registered” mention at the bottom of the window, as you have not yet provided it a licence key:

You can now either:

  • Use LotAtc as it is, in demo mode (unregistered), in which you’ll be limited to one connexion and 10’ of use per execution of DCS/LotAtc server per client.
  • Or, if you’ve bought a licence, you should now copy/paste the lotatc.key file you received by e-mail following your purchase (it can take up to 24h) into your {UserHome}\LotAtc 4 DCS\Data\Client\ folder.

This folder should have been automatically created by the first launch of the newly installed application; alternatively, you may create it manually.

{UserHome} is your windows account personnal folder. If you have a default windows installation then:

  • with Windows XP, {UserHome} is C:\Documents and Settings{your_windows_username}\
  • with Windows Vista or 7, {UserHome} is C:\Users{your_windows_username}\

The next time(s) you’ll launch LotAtc 4 DCS, you’ll not get the “Not Registered” message anymore, and you’ll be able to use the application without the demo limitations. Refer to the client user manual to see how to do this and have fun!

Uninstallation

Uninstalling LotAtc 4 DCS client is automatic. Execute the uninstaller via Windows start menu (or the .exe directly in the LotAtc client folder).

Please note that the uninstaller removes all files in the client installation directory, but will not delete the relief database, nor your licence key that are in another folder. You may then uninstall and re-install LotAtc 4 DCS on the same computer without having to worry about the database or your licence.

If you reinstall your system (Windows), don’t forget to make a back-up of the licence key (e.g. keeping the mail, have a back-up copy…).

If for whatever reason, you want to remove this licence key file too: do it manually. If you do so, don’t forget to save it elsewhere if it’s your intention to re-install LotAtc 4 DCS client later.
