I've noticed after a few iterations of MSFS as well as my reinstalls that when honeycomb software is installs, it overwrites the exe.xml and obliterates whatever else was in there: FSUIPC and realsimgear interface. Once this happens, it is very difficult, from a user standpoint, to rebuild the exe.xml so that everything works.
Here's what I've rebuilt, but I'm not sure it will allow both components to work unfortunately.
