How to Download Super Street Fighter IV Arcade Edition for the PC for Free?

Does anyone know how to download Super Street IV Arcade Edition for the pc for free? I've checked multiple videos and links, but I can't find it. Some stuff has some survey junk and another was just a video. If possible, can the instructions or links or whatever not have any surveys to answer first or something. Is getting the game through downloading even legit? Nevermind... But still, please help me. Please. Pretty please with cherries on top. PLEASE!
