Hi Raja,

Have you unblocked the DLL and GHA files?

http://wiki.mcneel.com/rhino/unblockplugin

thanks a ton !! will ....it is working perfectly...

by the way why is the c# script still in red in the demo files and the same happens planktonturtledemo file as well..!

Thanks in advance !

Can you post the error messages for one of the c# script components?

In all likelihood the problem is that the script component is looking in the wrong place for the Plankton assemblies. To fix this, right click on the script component a click "Manage Assemblies". You can use this dialog to browse for the DLL and GHA files and replace the current ones.

Usually Grasshopper picks up this problem when you load up the definition. Do you remember seeing an error dialog with a path in it that contained Daniel's name in it?

Hi Will, 

I met the same error and have tried to redirect the dll path as you suggested. However, the C# componet still appears red. Following is the error message:

1. Error (CS1705): Assembly 'PlanktonGh, Version=0.3.0.0, Culture=neutral, PublicKeyToken=null' uses 'RhinoCommon, Version=5.1.30000.10, Culture=neutral, PublicKeyToken=552281e97c755530' which has a higher version than referenced assembly 'RhinoCommon, Version=5.1.30000.7, Culture=neutral, PublicKeyToken=552281e97c755530'

Could you please let me know how to solve it? Many thanks!

Hi - this looks like you just need to install the latest Rhino service release.

ah...i see. Let me try. Thanks Daniel!

Hello 

I still have problem loading the plug-in I am trying to follow the 

" right click on the script component a click "Manage Assemblies"

but still doesnot help please see attached, 

Thanks,

Arian, did you use the "Manage Assemblies" dialog to replace the assemblies (by browsing to their location on you computer)? What is the error message that you're getting now?

Hi, im trying David Bachman's script for growing disk from -  http://www.grasshopper3d.com/video/growing-disk but i am getting an error in the python script used :

"

Runtime error (MissingMemberException): 'NoneType' object has no attribute 'Halfedges'
Traceback:
line 14, in script " 

I have installed the latest v4.0 of Plankton. I believe i installed it properly .. unblocked then copied to library. Can anyone help me out with this ?

Hi Parivardhan, I don't think the issue here is with Plankton. Try connecting a mesh directly to the "PMesh" input of the Python script component.

The error here is telling you that, in your case, PMesh is not a PlanktonMesh, it's null.
