According to the specifications on the official website, the software isn't compatible with Windows 8.1. However, I recommend you download it and then apply a compatibility tweak. After the software has been downloaded, right click the installation package and go to Properties > Compatibility. Choose Windows 7, save the changes then right click it again and select Run as Administrator. Follow the instructions and the software will run normally.
