hello siegfried and welcome to the forum!! The only software that is able to work as 'remote' for Oly camera is the Olympus Studio 2 Pro. Unfortunately it won't work with live view (like the canon)
connect the camera to your PC just using plug usb cable and on the camera menu select control! Yesterday I've installed this program and yet I'm still exploring it!
