• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS Using SimToolKitPro on a remote computer with MSFS

After a lot of trial and error I finally managed to get SimToolKitPro running on a secondary Windows computer, connected to my gaming computer running the sim.

Since there seem to be some interest in this and no guides I can find I am posting how I got it to work here!

This thread by Dutch got me starting and it's actually from that most of the settings come.

First of all, on the gaming computer you don't need to install anything special, Microsoft Flight Sim runs its own simconnect server, you just need to set it up properly.

Find the SimConnect.xml in the Microsoft files, usually somewhere here:
C:\Users\[user name]\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache

Add a new connection to that xml file:
<Descr>Global IP Port</Descr>
<Address></Address> !!Set the IP of your gaming machine
<Port>7421</Port> !!Can be another port if you like

That is all you need on the gaming machine side. No other simconnectserver needed.
You will probably need to open some ports in the firewall here though. It might be the FlightSimulator.exe that needs permission, I am not sure. For now, I just disabled the firewall altogether internally (I know, not a good idea, you have been warned!). Once I figure what program needs permission I'll update this.

On your second computer running SKTP you follow the usual SKTP installation and you set it up to use a remote computer (see the STKP instructions). To get it working you will however need do add a SimConnect.cfg to the STKP installation to get it to understand it needs to connect to the gaming machine.

Create a SimConnect.cfg in the app folder in you STKP installation directory. It is probably somewhere here:
C:\Users\[user name]\AppData\Local\simtoolkitpro\app-0.6.32\

It needs to contain the following, matching the IP and port number above:


On the secondary computer you probably need to allow SimConnectServer.exe through the firewall.

That is all, connecting after you have spawned in game should give you a green connection on the secondary computer and it should work!
