Is this compatible with Windows 10?
No, the software is not compatible with Windows 10. Based on the information on the developer's page, you can install this application only on the following operating systems: Windows XP, Vista, 7 or and 8.
However, I see their new version was developed to run on Windows 10: Windows XP, Vista, 7, 8, 8.1 or 10.
