#532688 Hello, the setup I have is P3Dv4, but also a "virtual" P3Dv3 installation to trick some of the older installers into installing sceneries into v4, however..that seems to cause vPilot to detect v3 as a sim, but because there's nothing there, clicking Apply causes yet another error of a missing default model. Is there a way to force vPilot to ignore v3?

#532689 You would have to remove the registry entry that stores the install location, or remove/rename the installation folder, or remove/rename the prepar3d.cfg file.

You could also just copy the default model from v4 to v3 so that vPilot finds it.
