If you double-clicked on the LS6 file, then it will open in Viewer Mode. This Mode does not show the Editor, and can be used for realtime walk-throughs and fly-throughs for presentations.
I'm not sure what you mean by commercial model though. Are you referring to an LS6 file that contains the Lumion Scene - camera views, effects, clips etc, and Imported Models?
