.Net Error

Hi,

When i want to open Grasshopper there are two things that happen. the first one is nothing when i enter the command 'grasshopper' the second thing (when the first doesn't happen) is a pop up that says that rhino had opened in safe-mode and that certain plug-ins might crash rhino. is asks if i really want to load that perticular Grashopper plugin.

when I click yes to the answer, I get a second pop-up. an error that says Rhino has failed to open the GrasshopperPlugin. It says that this plugin is a .Net plugin and i do not have any .Net support on my computer.

Anyone can help me with that?
