How encrypt my project?

[Raphael Rpg Games]

Hi guys, the demo of my game's already finished, all prissy and everything, but I can not "encrypt" my project.
In fact, I can even encrypt it, but whenever I try to install it, there are several errors, missing files, and a lot of other things.

So I wanted to ask my colleagues aki, a way of being able to protect all the files of my game so that whoever plays it,
can only open the game executable, and nothing more. (Summarized: a lowered to play? then you'll just do that and nothing else.)

Any good idea to protect what you have, please tell me. Can password on folders, a form of concealment (Well secure)
or other method of encrypting games you know. Everything so that it arrives to your PC protected from all malicious gossips.

The RMSusano'o seemed to be really good, but it does not encrypt folders Graphics (most important for me) and no Audio
(okay, not the RMXP also encrypts the audio folder), but I want to be able to protect the most of my game, since 70% (or more) of
My game's graphics were created by me and others edited, so do not want any "wise guy" getting my graphics.

Please people, I count on you to help me!
