• 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.

    FSX Error with ModelconverterX 1.70 for FSX

    GaryGB and Arno, I haven't made any more attempts to get MCX running on my computer since my last post. I installed v.1.7 on my Windows 7 laptop and it runs OK there if I need to use it I'll go to my laptop. Franzi was the OP on this thread so I'll bail out for now and hopefully you can get his...

    FSX Error with ModelconverterX 1.70 for FSX

    GaryGB, even after all these years of maintaining my own computer I still don't feel confident working with the BIOS settings. There is a fairly easy to understand AI explanation online for how to turn off the integrated graphics on the Gigabyte G41M-ES2L motherboard. I may try that but I have a...

    FSX Error with ModelconverterX 1.70 for FSX

    Windows Device Manager is showing only my add-on GTX 1070 graphics card, status "working properly".

    FSX Error with ModelconverterX 1.70 for FSX

    According to the specs for my motherboard (Gigabyte G41M-ES2L) it has Graphics Media Accelerator(GMA) X4500 (DirectX 10) onboard graphics. I've been flight simming ever since I got my original HP computer in 2001. I don't recall ever running the computer with just the motherboard graphics, I've...

    FSX Error with ModelconverterX 1.70 for FSX

    UPDATE: Arno, I just now attempted to run MCX 1.7, got the same "Error Handler" prompt as before, and this time made sure to hit the "send report" button. Hope that helps you.

    FSX Error with ModelconverterX 1.70 for FSX

    Give me a couple minutes with MCX 1.7 installed and I'm pretty sure I can duplicate the Error Handler message and I'll be sure to click the "report error" button.

    FSX Error with ModelconverterX 1.70 for FSX

    Arno, thanks for your help. When I attempted to run MCX 1.5 and 1.7 I got the original Error Handler message from my original post: "An unexpected error occurred." After I installed .NET 8.0 and tried to start MCX 1.8 and got the three EULA/copyright "I agree" screens you see when MCX starts up...

    FSX Error with ModelconverterX 1.70 for FSX

    Thanks, GaryGB, I didn't see any options on the NVIDIA control panel that I felt comfortable messing with so I appreciate you confirming the OpenGL capabilities of the new graphics card. I wish my original "Error Handler" error message had listed a location of the problem like on Franzi's post...

    FSX Error with ModelconverterX 1.70 for FSX

    Hi Arno, I assume you're referring to my error problem here. My OS is Windows 10 Home (x64), v.22H2 (build 19045.6216). Graphics card is NVIDIA GeForce GTX 1070, current driver is v.580.97 released 8-12-25 and installed by me 8-28-25 as part of troubleshooting this MCX error. The card itself was...

    FSX Error with ModelconverterX 1.70 for FSX

    Rhumbaflappy, thanks for the post. I know MCX is not the problem here, gotta be some interface glitch. I followed your instructions... Removed and reinstalled MCX v. 1.8, deleted SceneryDesign.org folder from AppData, tried to start MCX and still got the same black-screen fatal error message...

    Just to follow up, I downloaded and installed DirectX 9 and I'm still getting the same black-screen fatal error message as I posted before. ☹️

    FSX Error with ModelconverterX 1.70 for FSX

    GaryGB, I will act on what you just now posted and see if I have any success. Thanks again for your help and if you don't hear back from me that I've been successful bring this to Arno's attention when you have contact with him. Maybe he can ID what my problem is. I know both of you are WAY more...

    FSX Error with ModelconverterX 1.70 for FSX

    Could the location or ID of the SDK be a problem? I am running FSX-Steam Edition and there is a SDK folder in the game files. I've run MCX versions 1.5 and 1.7 working with FSX-SE and never had a problem until v. 1.7 stopped working a few days ago and I posted here. I am frustrated that I can't...

    FSX Error with ModelconverterX 1.70 for FSX

    I reinstalled all files for MCX v. 1.8 per your post above and Arno's readme in the v. 1.8 download. Put MCX in its own folder in C:\ drive. Still getting same black-screen error as last night: "Fatal error, blah-blah... External component has thrown an exception." I have no clue what external...
