Someone else has already answered your question (thank you for doing that!!), but just so that there's no misunderstanding:
- Make sure to place the entire unzipped "14 Nights With You" folder inside the "game" folder.
- DO NOT move or place the files individually. Again, make sure the only thing you move is a folder called "14 Nights With You".
- DO NOT place the "14nightswithyou-free" or "14nightswithyou-paid" folder. You need to unzip it first.
Make sure to follow the instructions listed on this Itch page! If you still need help, please let me know ^^
