How to launch this program? I've downloaded it many times and it doesn't have an .exe file!
I have downloaded the application but the package is actually the source code of the application. However, there is a solution to this. Access the link below which leads you to the SourceForge website. The latest version has an EXE file compiled and ready to be used.
