There is no information related to the compatibility with Windows 10 for version 7.7 since I can't download it from the official website. There is versions 10 that can be installed successfully on Windows 7, 8, 8.1 and Windows 10.
I've installed the application successfully from the following link: https://www.nfive.com/index.php?SID=ICSESSKEY:Xn58f873c3df345
As a personal opinion, I don't think the old version will run on Windows 7 primarily because you need the drivers to be compatible. The software installs some drivers related to license.
