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. This would make distributing Rainmeter skins to end-users problematic at best.
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.
The approach consists of tweaking a feature of HWiNFO that was implemented years ago to support using the software with the now long-dead Windows Sidebar gadgets. This allows you to output the current values of one or more sensors to the Windows Registry, where it can be easily accessed using the Registry measure in Rainmeter. A distinct HWiNFO plugin for Rainmeter is no longer required.
All skins that use HWiNFO will need to be changed. While the new approach is actually easier to configure for the end-user of your skins, it is significantly different, and requires that skins be adapted to work.
This thread can be used to discuss this change, and help folks who need to revise their skins to adapt to this new approach.
This requires that you get the latest 7.02 or later version of HWiNFO

Just remember that it was version 7.0 that broke things, and it requires 7.02 or later to fix them.
Then carefully read and follow this guide
