Hi,
Since some time ago, the integration with our plug-in has been handled by a corresponding third-party company that provides their vegetation packages. We continue to prepare it exclusively for our The3dGarden plant collections. Thank you for your understanding.
The mentioned catalog (which hasn't been updated for a long time) does not recognize the new FP7/FP8. Currently, you can manually unpack all the content from the lib folder (for example, by opening it in 7Zip) and map it from the Library Browser's UI. Alternatively, you can import the attached registry key to register Forest Pack for these old catalog tools. I hope that helps.
Best regards,
