Somebody else had just asked about this a week or so ago. I figured you'd check out the thread. Anyway, the reason you can't install it separately is that AHFilm is actually part of the game program. How it works is it records the data stream that's happening while you play. Things like what your plane is doing, its position on a given map, where you're looking, what the other planes are doing, etc, When you view a "film" you aren't looking at a video of what occurred, you're looking at that recorded data stream being fed back into the game engine with a few other controls that let you fast forward or rewind along the stream or change your view, etc. It's a separate .exe file but it's actually part of the overall AH program. There's no separation to separate it. Hope that made sense.
