Thank you for including a screenshot!! From what I can see, you've moved the wrong folder. You should be using a folder called "14 Nights With You", not "14nightswithyou-free". Either look inside that folder for it, or rename it accordingly.
Please refer to the installation guide shown above for more information!
Edit: If you manage to solve your problem, feel free to edit (or remove/delete) the screenshot from your comment ^^
