I've accessed the official website and these are the system requirements available for this software:
System requirements
Multimedia computer (Pentium 1.6GHz or better)
Windows 2000/XP/Vista/7/8, including 64-bit
RAM: as recommended for your system
~100 MB free hard disk space
1024 by 768 pixel or larger display
CD-ROM drive (CD version only)
As you can see, Windows 10 is missing from that list. Unfortunately, I can't test the latest version of RulesMaster Pro since its license is commercial and requires purchasing before you can actually install it on your PC.
Get in touch with the developers and ask them about this using the following email address: [email protected]
