Error loading plugin (grasshopper)

Hi everyone!

Recently, using grasshopper, a boolean error produce force close of the app with rhino. After that, this message pop up every time. I already tried to open and load part by part the plugin of grasshopper and reinstalling rhino8. Does anyone know how it could be resolved?

Try Repairing Rhino first. Did you install as admin? Another thing to try is to uninstall and reinstall as Admin (there could be an anit-virus program blocking portions of the install)

Lastly it could be due to a plugin conflict of some sort.

Can you run SystemInfo command in Rhino and post the result?

Hi Japhy, already try to reinstall the app, same error appear. The first time I install the app can´t remember If I install rhino as admin, so I decided to uninstall and reinstall it, same error. I don´t have another antivirus program besides windows defender.

Any particular reason you are running .NET Framework 4.8.9221.0 ?

Try switching it back to .netcore

To be honest, I didn’t even know it had that configuration. I changed it through the SetDotNetRuntime command and already function! thanks.

Just in case I have the same problem in the future, using that command is the correct way? or I should change the framework with a different process?

I think you did it correctly. Here are the options.
