Real Arcade versions

Can anyone tell me how to get rid of the old versuion of Real arcade and upgrade o the new one? I have what seems to be called a "Special Edition" of the Ral Arcade player from Reader's Digest. And it did not have my full version games on it. I can only download demos and possibly buy games for it but the games I already own are not on it.I do not want it on my computer at all even though it is a free version. I just want the New and latest version of Real Arcade and nothing else. Can somebody help me?
