(REPOST FOR NEWCOMERS)
this is how to play Chapter 3!
first you will need to download 7-zip (also set it up)
after downloading that, download 1.1.3 (Aka chapter 3)
once the downloads are done, right click on the media player file (aka the chapter 3 file) and go to the 7-zip section
then you want to go and click the top option, archive
you should see the game
after that, create a new folder and extract the game into that folder
i hope this words
