Can't install plugin fro grasshopper in 21

[Anonymous]

Hey,
I am having trouble installing the plugin for 21. It worked well for 19, but I can't even load it fro 21. Not sure what to do. I have removed the add-on in 19. Also I am wondering how to un-intsall and completely remove the old add-on, so i can get the latest. How on earth do I do this?

Thanks,
Eoghan
