What is the latest version, please? Will it work on Windows 10? Is there a software/licence cost?
Yes, the software works properly on Windows 10 Pro x64 bit. I've downloaded the official version from its website and installed it properly. The software works normally and there were no errors or weird behavior.
Also, the product is free to download and use. After installation, I've checked all the built-in menus, and no registration was shown.
