Not a bad idea ! It works except when moving the hat in intermediate positions (45°/135°/225°/315°) At least in my case with a Thrustmaster T16000

Old topic but it happened to me today and the file to look out was in my case %APPDATA%\Lockheed Martin\Prepar3D v4\add-ons.cfg

@Gabe777 I can't tell you exactly what did the trick since I've tried a few different configuration but it's clearly related to the "Application Control" settings in the Firewall tab I've manually added all the Trainer executables (roar.exe, Aviation_Trainer_Launcher.exe, supernav.exe, GTN Simulator.exe) and set them as Super Trusted Application Control is ON, with first slider on max (Network firewall screens all programs) and DefenseNet set to manual Did a reboot and now it's working fine Hope this helps And I suppose that something similar could be achieved with Comodo. I may try it again

@Gabe777 OK I've just tried with Zone Alarm and it's about the same trouble : the GTN Trainer fails on one DLL and then crashes The Garmin software has clearly some issues when a third party firewall is installed Edit : after fine tuning ZA, it works OK

@RXP Since last RXP version did not solved the problem for me, I've just tried what Gabe777 did : uninstalled Comodo Internet Security Suite and voilà ! It did the trick I didn't reinstall Comodo yet

@RXP I've just installed RXP V 2.5.13 and still the same issue :(

@RXP I will then wait for this update and won't try what Gabe777 did (I'm also using Comodo firewall) to be sure your workaround is fixing the issue

Did a fresh reinstall after major Windows update (1809) Still the same problem........ What do you mean by "Make sure you configure the trainer for the GTN 750" ?

Did you try a few times ? It happens that you get a black screen but eventually it'll work

@Mark : I wouldn't say it's useless ! As far as I'm concerned once all the alert popups have been closed everything is working smoothly

Salut Jean-Luc et très bonne année à toi ! For your information my situation is still the same : I did install the latest RXP release (2.5.11), but the same issue occurs

Since I've got 2 versions of the Garmin Trainer (6.21.0 working OK and 6.50.1 with the loadlibrary issue) I'm using the 2 variables documented in the RXP manual to point to each of one : GTNSIMDATA & GTNSIMPATH

Version 2.5.9 installed with Garmin Trainer 6.50.1 Same issue Here is the rxpGtnSim.dll.log : 18/11/25 08:28:02.803 47824 - ] # rxpGtnSim64.dll version 2.5.9.0 18/11/25 08:28:02.802 47824 INFO ] 18/11/25 08:28:03.975 47824 INFO ] using: D:\Users\web2\Documents\Prepar3D v4 Add-ons\A2A\SimObjects\Airplanes\A2A_C172\checklist.gtn 18/11/25 08:28:04.038 47824 WARN ] not found: C:\ProgramData\Garmin\Trainers 18/11/25 08:28:05.440 22988 INFO ] 18/11/25 08:28:06.118 02960 INFO ] GTN: 00 ..\..\src\krnl\krnl_lib\sim\tsk_win_prj.c(188) Error: LoadLibrary failed to load iop_c.dll.

I've got an integrated intel card but i'm not using it My main card is an NVIDIA GTX 1080. I nevertheless checked the use of the main card in the windows settings Regarding your last post : Windows Defender policy couldn't be an issue here since I use Comodo Internet Security (and I did test the Trainer disabling this one)
