I vaguely remember seeing something like that before. I don't think it was related to the type of license or version, but trying to do that "double click simulation" process.
I'll second the recommendation of passing it as an argument to the actual application; you'll want to include things like profile, ARX extensions (via "/ld" and "/product" arguments) as appropriate. Double-clicking from an Explorer window will have the same problems of version, application (TrueView, Navisworks, Civil3D/other verticals, etc.) etc. as with your application. You might want to consider a right-lick menu instead with a variety of appropriate "Open with/as..." options.
