I downloaded Pyxel Edit, and when I unzip the file the program dissapears.

  Hi!  So I bought and downloaded pyxel edit today, and after that downloaded it.  Once I downloaded the zip folder, i unzipped it with whatever windows 10 uses to unzip, and everything in the folder but the actual program got unzipped.  The program just disapeared.  I've looked everywhere and I couldn't see any cases exactly like mine, and I was wondering if anyone could help me figure out what to do.  Thank you!
