Is it possible you have another copy of the file somewhere on your PC?
What I think sometimes happens is that when multiple copies exist, GH loads the one (typically in your downloads folder) which isn’t unblocked, meaning it won’t work, even though the one in the libraries folder is unblocked.
all works fine! I followed the instruction in the pdf. Thanks again
You may also find you need to turn COFF loading off (by typing GrasshopperDeveloperSettings
from the Rhino command prompt and unchecking the box), then restarting Rhino.
Since Kangaroo 2 comes pre-installed on GH for Rhino 6, would it be okay to download and install Kangaroo 2 on Rhino 5 for ppl that have both Rhino 5 and 6? so can they be used together.
