The FSE Client (sometimes called the "agent", or just the "client") is a stand-alone program that interacts with your Flight Simulator and communicates with the FSE Game World server to send information such as fuel status, flight time, and location back and forth between the Game World and your simulator.
There are three (3) different FSE Clients. Which one you need to use depends on your simulator version and your operating system.
The FSUIPC client is compatible with all versions of Microsoft flight simulators (FS8, FS9, and FSX) and Prepar3D. It requires the FSUIPC module by Peter Dowson (either the freeware or the payware version).
The SimConnect client is only compatible with Microsoft FSX or Prepar3D, and uses the SimConnect library to provide the interaction between your simulator and the client.
The X-Plane client is a python script. It requires Python to be installed, and it uses the Python Interface software for X-Plane by Sandy Barbour. The X-Plane client and supporting software can be installed on any operating system (Win, OSX, Linux).
At the beginning of your flight, the client configures your simulator to match the fuel and assignment payload state that is reflected in the FSE Game World. The client also ensures that you have the correct aircraft loaded into your simulator and that you are at the correct airport.
At the end of your flight, the client sends information back to the FSE database, such as how much fuel is remaining in your aircraft (and in which tanks), where you landed, etc. This will leave your aircraft in the same "configuration state" for your next flight, or for the next person who uses the aircraft.
Since the client needs to communicate with the FSE Game World, you must be connected to the Internet in order to use FSE. However, you are only required to be connected to the Internet at the beginning and end of your flight. There is no communication between the client and the server during the flight, so if you need to disconnect from the internet while flying, you can.
Several FSE users have reported issues installing the SimConnect client with FSX:SE. FSX:SE will call itself FSX in your Windows registry if installed first, however if there is another FSX install already on your system then FSX:SE will call itself FSX:SE in your registry. Most stand-alone add-on programs, including the FSE SimConnect client will look for and install to the FSX entry in your registry.
If you wish to use the SimConnect client with FSX:SE then you will need to conduct a complete uninstall of FSX (including acceleration if applicable), before installing FSX:SE. When uninstalling FSX, be sure to use the FSRegistry Repair Tool from F1 to remove FSX registry entries BEFORE installing FSX:SE.
If you wish to run multiple installs of FSX, then the best option is to use the FSUIPC client.
The FSE client does not usually interfere with other flight simulator add-on software, so feel free to continue using other tools that also enhance your simulation experience. Some popular examples are the various flight planning & moving map applications, FSPassengers, VATSIM, and the various weather enhancing add-ons.
