For rFactor, rFactor2 and derivatives sim (ARCA Sim Racing, Formula Truck, Stock Car Racing Game), is available the telemetry control feature and for this reason you must install both the plugin and configuration file. The operation must be performed only once for each installation of the game that you want to use but in the case in which the plugins were to suffer an update then the client will signal the need for reinstallation.
For rFactor (games and derivatives) the plugin will be installed in the Plugins directory without changing its name.
RFactor 2 you must install both the 32-bit and 64 respectively under Bin32/Plugins and Bin64/Plugins. For all the games then need also install the configuration file on the root installation path of the game.
After each installation the client performs a check, when the icon of the plugin becomes green means that all the plugins and configuration files are properly installed. A further check is performed when the plugin starts working or when you turn on the game, it checks the version of the plug and, if not corrected, the icon turns red.
