Hi Gary,
The help should be accessible from within RIO by pressing F1 with a component selected. You can also manually get to the help file and the demo directory by navigating to the installation folder.
For 10.2 (Tokyo) and earlier, the components are installed into C:\Program Files (x86)\Raize\RC6. However, for 10.3 (Rio), Embarcadero created a custom GetIt Installer for the components. They are no longer installed in their usual location. Instead, they are installed in: C:\Users\Public\Documents\Embarcadero\Studio\20.0\CatalogRepository\KonopkaControls-260-6.2.3
