Martin Malik, the author of HWiNFO, has graciously worked with us to find a solution that will allow the software to be used for personal, non-commercial use in Rainmeter without having to purchase a license, while keeping his ability to monetize his application when used by commercial entities.
This would make distributing Rainmeter skins to end-users problematic at best. As of version 7.0 of the HWiNFO hardware sensor monitoring tool, the software has changed to require purchasing a yearly 'Pro' license in order to use the Shared Memory feature of the software that allowed it to interact with the HWiNFO plugin for Rainmeter.
