generative modeling for Rhino
I just encountered the same problem. When I loaded either grasshopper.dll or GrasshopperPlugIn.rhp in the PluginManager it didn't load and said: "Plug-ins built for 32 bit Rhino will not load in 64 bit Rhino."
Even if I uninstalled and reinstalled the most recent GH-built it still gives the same feedback...
I'm running Win7 64bit with the newest versions of GH, Rhino 4.0 and 5.0 WIP (installed and updated everything today!)
Is there a solution? Would be great!
Problem solved! I've overlooked taz's answer of copying the whole GH-folder to the rhino 5.0 WIP folder!!
Now it works perfectly!
Thanks for the discussion and sorry for my not important comments... ;)
