Problems installing Ladybug with Rhino 5

Hello everyone! Looking for some help. I’m trying to install Ladybug on Rhino 5 and Grasshopper The only Ladybug versions available I think are for Rhino 6 and 7, and when I’m trying to install them I get an error. Do you have any idea where I can get a version for Rhino 5? or what I should do in this case.

Thank you!!
