I want CORAL PLAYER.Can sombody plz tell me where to get this media player?

I downloaded a movie.It plays a message that the so called coral player is reqd. to play the movie.Is this a scam?If yes it is a large file ,about 750 MBs,if it is not a genuine file to be played ,what does it contain?Should I simply delete the file ?or is there some way it will work?
