C:/Users/MyName/Downloads/Crashtastic.exe is not a valid Win32 application

That is the error I get after I have installed crashtastic.exe from the website. I ran it from the downloads folder, though I'm not 100% sure it downloaded correctly because it is only 17kb and it took only 20 seconds or so.

Hopefully someone has the answer.

Thanks ahead of time, Xapien!
