I'm sorry about that. What problems are you having?
Click the button with the three dots to the right of the filepath (the string of text that starts with "C:/" or "C¥" in this case), and it should take you to a box where you can select where you want the game installed. If that doesn't work, you can try extracting the game files (in Yummy Breakfast.lzh) with a program like 7zip, if you have it. I hope this helps!
