SDK Toolset (FSX)
The SDK is actually a collection of task-oriented SDKs.
There is no single tool that you run,
rather it's collection of tools, each of which perform seperate tasks.
Some of these SDK tools will call other SDK tools.
The majority of tools are stand-alone, and launched outside of the sim.
Depending on version, a few tools are launchable from the in-flight menu.
You should use the appropriate SDK version to match your version of FS.

All other tools are run/started from outside the sim GUI.
