The one from the link you posted and the one from the link I posted seem to be 2 different programs as they are of a different size.
I downloaded the one from my link and unzipped it, and it worked Ok. Good luck!
Edit: Now I also downloaded the one from your site and it gave me the same error.... but after checking the readme file
, it says that it should be unzipped in "C:\snaketracker\". I tried it and it worked Ok. And yes they are 2 different programs.
