Migration grasshopper plugin Rhino 7 to 8 - not loading

Hi there,

I’m a little confused. some of the plugins I had under R7 are not working (showing in toolbar) under R8. (e.g. Pufferfish, Charmeleon, and others)
Some says some plugins should show/work that arn’t showing under the toolbar for me. (for instance chameleon plugin)
** OFC I’ve unlock them before using them.

Basic questions:
1 - is the folder path still the same for GH plugins under R8 as in R7,6 ?
- %AppData%\Roaming\Grasshopper\6\Libraries
2 - Not sure to fully understand, but is the problem related to NetFrame. going from 4.8 to 7 ? this post propose a solution. Though it didn’t changed anything for me when I tried this fix.

Thank you community :slight_smile:

Hi Charles -

No, that would be %AppData%\Grasshopper\Libraries\ (that is, without the 6).

That’s the likely culprit, yes. If a plug-in relies on functions in .NET Framework 4.8 that are not available in .NET Core, it will not run in Rhino 8 out of the box. The plug-in developer should update the plug-in, or you can use the SetDotNetRuntime command to switch the runtime in Rhino (or use a different shortcut icon with the /netfx attribute).
