The current version of Gerotor Design Studio is 2021.1 (released 3rd May 2021).

Gerotor Design Studio is Windows-based software (compatible with Windows XP, 7, 8, 10).
It is licensed on an annual basis but can be downloaded for free and used for a 30-day unlimited use trial. The trial has full functionality, except for the resolution of the Inner Rotor CAD models and output co-ordinate files. This restriction is lifted on purchase of the annual license.

The basic cost of a license is 995GBP per year. There are some additional fees depending upon the licensing options taken.

Support, bug fixes, and feature upgrades will be added at no extra cost to licensed users. Updates and upgrades will be automatically downloaded and installed using the included Update Installer software, so long as the PC has an internet connection.
