The current version of Gerotor Design Studio is 2.1.8 (released 31st August 2017).

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, exactly the same as the fully licensed version. After 30 days an annual license must be purchased to continue use of the software.

The basic cost of a license is 995GBP per year. There are some additional costs 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. This ensures that the version you are using is always the most up to date available.
