The software is available for downloading from its official website, if you plan to test it, but the problem is that the website doesn't allow connections from all the countries. I've used a proxy server to access the website.
Use Google Search to search for a web proxy then input the following address in the navigation box (not your browser's!): http://www.wincfass.com/
Click the Download section on the website and then download the software to test it. This is the only way to obtain WINCFASS.
