I am in a state of desperation. With the intention all-along of exporting the game to a USB drive, I am  just now realizing that I have no idea how to run the game on a separate computer once the file is downloaded/exported (which means that if you've downloaded the file on this page, you're probably encountering the same error-- sorry).
I am including the Runtime package when running the "Create Game Installer," so the file is coming out with all the required resources... but no executable file.  Here is a screenshot of everything in the folder once the game has been exported and installed. Can anybody tell me what file in this piled-up mess I need to run the game itself? 
I want to give this to her tomorrow. I have already spent a few hours troubleshooting this, so I am really hankering for answers if anybody can offer one. 
Thanks.
