Rhino 5 does not accept gh files

Hi all,

I just partitioned my Mac book pro with windows 7.

I installed Rhino 4 and then Rhino 5 Beta. They are both working fine.

However, when I installed Grasshopper 0.9.0014, the Grasshopper folder will not be created in plugin folder of my Rhino 5 Beta as it does in Rhino 4 while it did in my last computer (pc,windows vista).

I copy/pasted the Grasshopper folder from Rhino 4 to Rhino 5 Plugin folder, but it seems like this folder is not functioning at all since when I drop any gh file for addons, like MeshEdit or Kangaroo or python, in the component folder, nothing new gets  created in component ribbon.

Please let me know if you have any suggestion.

Thanks,

Naciem
