I'm having a similar issue as other QnAs where UEReferenceApp.uproject returns an error when opened, and when I try to generate visual studio project files it gives me an error. I've ensured I'm on a release build and the correct files are in jsbsim-master\UnrealEngine\Plugins\JSBSimFlightDynamicsModel\Source\ThirdParty\JSBSim\Lib
and not LibDebug, the error is below:

The error indicates you need to install another c++ toolchain through the VS installer.

I'd installed every possible toolchain through the VS installer, the only way to get it to work was to remove the reference to 14.29.30136 C++ toolchain in the BuildConfiguration.xml. I was then able to generate the visual studio project files from ERReferenceApp.uproject but received a new error:
