Note that “Direct3D 11” and “DirectX” are different things. Using XInput of a particular version is different from using the Direct3D 11 APIs that come built-into Windows.
(Yeah, Microsoft could do better on making all of this clear)
You will need to run one DirectX Runtime Installer that includes XInput. You will also need to run the MSVC installer for the runtime for the version of MSVC that you build with, and perhaps for other dependencies you bundle.
The best way of doing this is to build your installer using WiX, and merge the other installers as MSM (merge modules) to hide it under the covers of your own installer UI
