Kangaroo will not launch

So I have just a quick question. I dragged and dropped the add-on Kangaroo multiple times and deleted it multiple times in Grasshopper. I have also copy and pasted the gha file in Grasshopper\files\special files\components. So far, however, there has been no update to the grasshopper tool bar. Is there any other way to fix this? The end goal is a 3d-voronoi with pipe connecting around the curves... But, when I deconstruct the brep and put pipe around it. It creates a second surface for every pipe. Kangaroo has a command that allows one to delete duplicate surfaces or curves. So, that's why I would like to figure out how to get it running. Also connecting the pipes after into 1 solid surface is troublesome as well. I have tried joining them but no dice. Lastly if you do know how to solve these questions please provide a tutorial or something as I am fairly new to grasshopper.
