I'm completely unsure about what software you are talking about. As far as I know and from the data I can find on the Internet, TechnoCad is a company that distributes CAD applications like AutoCAD Civil 3D, SurfMate, RebarMate, etc. not a Windows program in itself.
As far as operating system compatibility and newer versions go, I recommend contacting the developers directly using one of the means displayed in the application's Help or About sections.
