So I found this funny horror game called crunchy (highly recommended) while watching youtube and decided I wanted to play it myself, but when It downloaded and I tried to open the file, it said I needed an app installer.  After a lot of trouble, I was able to install an app installer that looked alright, but then found out it only works for microsoft products. After using an app called RAR opener, I was able to open the file, but now it's saying the code was not found and to reinstall the program. Anyone have any idea how to properly install the game so I can play it?
