I too looked at their web-site and their product description does not appear to exclude Win 10 -
Support 2000/XP/2003/Vista/7/2008/8 etc. platforms
The 'etc.' suggest to me that it should run on 10. I would be inclined to download and install it and see what happens. If it doesn't work - or doesn't work very well - you can always uninstall it. The worst that can happen is you get a pop-up when you try to install it saying 'This application is not compatible with Win 10'.
I believe I am correct in saying that most software designed to run on Win 8/8.1 will run on 10. In any case, if you take a look at the Win 10 section you will find people successfully running very old software on Win 10, even stuff written for Win 95 !
