If you want to stick with Windows only solution you must to install the ASCOM drivers for the Orion Starshoot and the DSLR. Once instaled you should be able to expose them remotely to the EKOS client (weather it is localy or remotely).
Regarding the DLSR there is a recent ASCOM open source drivers here : www.cloudynights.com/topic/625568-ascomd...-camers-canon-nikon/ . For the starshoot the driver is availblable on the product page : www.telescope.com/Orion-StarShoot-AutoGuider/p/99565.uts

AFAIK, the EKOS local mode is not avaible on Windows, but using remote mode with 'localhost' or 127.0.0.1 as remote adress will do the same. Actually, on other platfom (at least on Linux) the so called "local mode" starts an Indiserver wich listens on 127.0.0.1.
