It seems that you're trying to install a program that was developed for Windows 2000 or Windows XP. If you are using a newer OS, you might encounter some compatibility errors. The program was tested on Windows 7 without compatibility features and worked flawless. After you downloaded the program and extracted the files from the archive, you need to right click on the Setup.exe file and choose Run as administrator. After you did this, the installation wizard should pop up. This will guide you through the process.
