This is what really pisses you off isn't it, this member used the tools at his disposal, namely the knowledge base here in this forum, and got his answer, when you would have spent ages reading through the litrature for the same result. I remember it took me a while, I think I ended up reading articles on 3 or 4 different sites because I wasn't comfortable downloading anything I didn't understand particulary for something as trivial as a porn game.Being on the internet, having a question, and using the tools at your disposal to find the answer yourself.
I'd say the most logical parameters for a novice would be the RPGMakerVXAce part, the RTP sounding like an internal thing liike an executable or library file. I know when I went looking for it all these years ago, I was confused about which thing I needed to download, the separate Run Time Package download sounding more like an extra to be used in updating/upgrading the full version.Next, comes the common sense application - Using the tools available to you (in this case a search engine) and using the most logical parameters (in this case RPGMakerVXAce RTP)
