After quite a bit of experimenting, I think we've finally found the correct way to start the CFS3 Model Viewer under Windows 11.
Don't run
CFS3.exe -m3dview.exe directly. Instead, create a shortcut to your normal
cfs3.exe and edit the
Target so that it reads:
"C:\Your CFS3 Folder\cfs3.exe" -m3dview
Replace the path with your own CFS3 installation folder.
For example:
"C:\CFS3 ETO Expansion\cfs3.exe" -m3dview
or
"C:\TOW Pt.1I 19 42-45\cfs3.exe" -m3dview
On my Windows 11 system this launches the actual M3D Model Viewer, allowing models to be selected and displayed. ETO and TOW Part 1 work correctly for me. One of my other installations still crashes after loading a model, but that appears to be an installation-specific problem rather than a problem with the launch method.
Hopefully this helps anyone who has been unable to get the CFS3 Model Viewer running under Windows 11. Thanks to chatGPT!!!
Caveat: In the BoB Update, the Model Viewer opens, but an internal window reports
"Mission fails to load." After closing that dialog, I can select an aircraft .m3d file, but it then CTDs. This appears to be specific to the BoB installation. both latest and an earlier version (which did not have the mission fails to load small window!).
