SuperSonico Installation Problem

Hello Folks,
I downloaded the Manual and 4 Files and used 7zip to extract the Setup file(Installer), but all I get is a Setup Folder but no .exe to run to install the game, so it recognizes the other 3 Files. Is there something I’m missing?

Thanks in advance

UPDATE: I have figured out that downloading the Setup Files from Internet Explorer wasn’t recognizing the Installer File as a .exe file. I instead downloading using Mozilla Firefox and the Main Installer was the .exe Setup File I needed, so with all the files it installed completely. Everything is working great! It’s a fun, challenging and cute game!
