Error: No Radiance installation was found

I am using the example file “annual_daylight” from Ladybug sample files. When I click the toggle to true for any of the example files I get this error message:

“1. Solution exception:No Radiance installation was found on this machine.
Download and install the version of Radiance listed in the Ladybug Tools compatibility matrix
1.4 Compatibility Matrix · ladybug-tools/lbt-grasshopper Wiki · GitHub

The error message is pretty clear. Did you follow the link to the compatibility matrix and install Radiance on your machine?

How can I tell which version of rhino I have? I have rhino 7 and it is up to date
