As it's stated on the official support page, this software version was specially designed for Windows XP. Although it is possible that this version can be used on a Windows 7 machine, I strongly suggest that you upgrade your software to a version that is designed to work properly on your OS. In case you don't update your software, your system can be affected by malware.
To download and install the latest version of the software, you can visit Software Informer to obtain a download link or the official website.
