G1000 Hardware. Issues with MSFS2020 and MSFS2024

Hello everyone,

I am experiencing persistent issues with my Flightsimbuilder G1000 hardware setup, and I’m hoping someone can help. Here are the details of my setup and the problem:

Setup​

  • I own two G1000 units: one configured as the PFD and the other as the MFD, along with the central Audio Panel module.
  • All three devices are recognized by my system.
  • I installed the drivers using the latest version of the Flightsimbuilder Launcher (v1.13.0). When I launch the software, it confirms that all devices are connected and marked as "OK."
  • I use both MSFS 2020 and MSFS 2024, but the hardware only works reliably with MSFS 2020.

The Issue​

Most of the time, after starting the Flightsimbuilder Launcher and launching MSFS 2020 or MSFS 2024:

  1. I load an aircraft with a G1000 (e.g., the DA42 by COWS), place it at a parking spot, and enter the cockpit.
  2. I use the ALT GR + left mouse click combination to place the PFD and MFD screens onto my hardware.
  3. Once I power on the G1000 using the master switch, the hardware often does not interact with the simulator. None of the buttons or knobs on the hardware work.
In approximately 6–7 out of 10 attempts, I encounter this issue. To resolve it, I have to exit the simulator, return to the desktop, and either reboot or fully shut down my PC. A simple restart is often not enough.

Attempts to Fix​

  • I have formatted my PC and performed a clean installation of the operating system, but the issue persists.
  • I have uninstalled and reinstalled the Flightsimbuilder software, removing all related folders before reinstalling, but this didn’t help.
  • I installed FSUIPC7 as recommended to better manage peripherals in MSFS 2020/2024, but I have not configured it since I am unfamiliar with its use.
  • I checked the FSUIPC7 log file and found a "WARNING Joystick ID is duplicated in Registry" for the MFD (Joystick ID = 7) and my Thrustmaster HOTAS Warthog throttle (Joystick ID = 6). I suspect this duplication might be causing the problem, but I don’t know how to fix it.

Additional Info​

I have attached a screenshot of the FSUIPC7 log file showing the warnings for duplicate Joystick IDs.

Questions​

  1. Could the duplicate Joystick IDs in the registry be causing the issue? If so, how can I resolve this?
  2. Has anyone else experienced similar problems with Flightsimbuilder hardware and MSFS 2020/2024?
  3. Is there a way to configure FSUIPC7 to prevent conflicts between peripherals?

Thank you in advance for your help!
 
Hi Pelmo,

Thank you so much for providing all of the details — they’re really helpful. We’ve noticed that a small number of users are experiencing issues with MSFS 2024. As we investigate whether this is a bug within MSFS 2024 or something that requires an adjustment on our end in the launcher, the information you've shared so far is invaluable.

Could you also provide a log file from the Launcher? You can find it in the following location:
%LocalAppData%\FlightSimBuilder\FlightSimBuilder Launcher
Just copy and paste this path into your File Explorer to access the log.

Lastly, could you try one more test for us? Please launch MSFS 2024 first, start your flight, and then launch the FlightSimBuilder launcher. Let us know if that resolves the issue.

Thanks again for your help!
 
Thank you for your response and suggestions.

I’ve conducted four tests based on your advice, and here are my findings:

  1. First Test:
    I launched the FlightSimBuilder Launcher first. I clicked on “Install Again,” then “Configure Again,” and finally selected MSFS 2024 before launching the simulator. Surprisingly, once I was at the ramp and ready to start the flight session, the G1000 hardware worked perfectly for the first time. I conducted a test flight around the airport, and both the PFD and MFD functioned without any issues.
  2. Second Test:
    I followed the same procedure as above but selected MSFS 2020 instead. Once again, everything worked without any problems.
  3. Third Test:
    Following your suggestion, I launched MSFS 2024 first. After loading into the ramp and getting the aircraft ready (with the G1000 hardware not functioning initially), I launched the FlightSimBuilder Launcher. This time, the hardware started working as expected.
  4. Fourth Test:
    I repeated the same process with MSFS 2020 (launching the simulator first and starting the flight session before launching the Launcher), and the hardware functioned correctly in this scenario as well.
Based on these tests, it seems that the most reliable method is to launch the simulator first, start the flight session, and then open the FlightSimBuilder Launcher when the aircraft is ready on the ramp. I’ll continue testing in the coming days, but for now, I plan to use this sequence to ensure consistent functionality.

I’ve attached the requested log file for your reference.

Thank you again for your help, and let me know if there’s anything else I can assist with!

Best regards,
Pelmo

Thank you for the update. It looks like maybe it wasn't initially installed for both MSFS 2020 and MSFS 2024 and that was the reason it didn't work in MSFS 2024. We will try some additional testing to see if we can recreate it.
 
I am having the same issue. I just don't have 2024. But when I start 2020 I can pop out the screens but the buttons and knobs do not work. Everything was fine prior to the latest update. Like you said, the only thing that will fix it (sometimes) is a reboot. I will try starting MSFS first then load the FlightSimBuilder Launcher to see if it will fix the issue.
 
Sorry for not replying sooner, but I haven’t had much time to test. Today, I tried both flight simulators, MSFS 2020 and MSFS 2024. I launched the simulators by starting your FlightSimBuilder Launcher first. I encountered no issues!

I first updated to version 1.14.1. Then, I used MSFS 2024. After closing the simulator and, without restarting the PC (previously I always had to restart it), I launched MSFS 2020, and everything worked perfectly.

Even the pop-up windows in MSFS 2024 are functioning without any problems. To be honest, it takes a bit of trial and error, but eventually, the pop-up windows can be positioned perfectly within your G1000 hardware, PFD, and MFD.

I hope that your FlightSimBuilder Launcher will remain stable from now on. If any issues arise again, I’ll post them here immediately.

Thanks again, and happy flying, everyone!

I have same issue were the screens load from cockpit ok but no button functions. I have Fredemont_Freds_Contrller_testor and all the buttons show ok also did control printer & devices test buttons showed ok. uninstalled FLIGHTSIMBUILDER launcher, did a reinstall. no luck. I found in game the G1000nxi was not installed after Feb 7th update. reinstalled started working . all buttons worked great on multiple flights on 3/4/2025. today relaunched sim tried flying my Barron G 58 NO BUTTON. FSBuilders does not have answer although very helpful on this issue. I use steam for sim
 
Today I uninstalled msfs2020 from steam then reinstalledmsfs2020 . Same issue NO BUTTONS. And no one has an no answer. All the money spent on junk & can't even use them for a boat anchor

Hi,


I had a similar issue with my FlightSimBuilder G1000, and I managed to fix it by following these steps:


  1. Uninstall the "FlightSimBuilder Launcher" completely and restart your PC.
  2. Before reinstalling, search your system for any remaining files or folders related to FlightSimBuilder. In my case, I had to manually delete the "flightsimbuilder-wasm" folder located in the "Community" folder.
  3. Reinstall the "FlightSimBuilder Launcher."
  4. Make sure the "Auto-Start Sim" option is disabled in the launcher.
  5. Click "Install again" once, then "Configure again," and finally select the version of MSFS you want to launch.

This process solved my issue, so I hope it helps you as well.


I'm really sorry that nobody from the company has responded to help you yet. After spending such a significant amount of money, it's only fair to expect a well-functioning customer support service.


However, I can personally say that my experience with FlightSimBuilder has been positive. I live in Germany, and after just a few weeks of use, one of my G1000 units developed an issue with the FMS rotary knob. When I contacted the company, they asked me to send all my units to a specific address. They replaced the faulty part and, since I was one of their early customers, they also updated the firmware of all three components (PFD, MFD, and COMM module) to version 2.0—something that could only be done at their service location at the time.


I honestly don’t understand why they haven’t reached out to you yet, but I hope you get your issue resolved soon!


Best of luck!
 
Alternately, you can bypass using the FlightSimBuilder Launcher software completely and use SPAD.next or Axis & Ohs to map your buttons. I'm using SPAD.next and everything is working quite well.

My only issue is that the LEDs on the comms panel aren't controllable so I don't get the little triangle indicators to show me which COM or NAV button I have selected. But hopefully that functionality will get added in a future firmware update.
