I'm so sorry for the late response!! I don't usually check itch T_T

I'm not sure if you've already solved your problem, but just in case: make sure you've deleted any older versions of the game!! There should be a "Ren'Py" folder somewhere in your documents/applications folder; and inside it should be a "14 Days With You" folder as well. Just delete (or move) the entire folder and see if that works! If not, you might've downloaded the wrong file ^^;

I have the same thing happen to me, but it was just the name of the file. It usually still has the update even if it's called 1.0. Have you tried to open it and it only had Day 1? Because if not, I think you should try and see if it does have the update.
