I keep getting this error, I’ve tried everything but I can’t solve it. Can you help me?
Are you running Rhino in Safe mode per chance?
You can go into Properties>Plugins and enable it if that is not the case.
No, I’m opening it as a normal Rhino 8, but even when I activate Grasshopper from here, I still get the same error.
What is your Rhino SystemInfo? (run the command in Rhino)
Lets repair your Rhino install. Go to Add Remove Programs / Rhino / modify / Repair
I’ve tried repairing it multiple times, but it still hasn’t fixed the problem. It was working perfectly until today, but I started getting this error when I turned it on.

You are in safe mode.
You also want your Nvidia to the primary OpenGL
I turned off safe mode, this is probably the problem, and I’m trying what you sent right away. Thank you.

@Japhy I’ve tried everything, but I’m still getting the same error.
So not in Safe mode and you are still not able to enable the Grasshopper plugin?
Lets disable 3rd party plugins and restart Rhino.
Unfortunately, it didn’t work. Should I uninstall and reinstall it?
A repair is better, so not likely to get a different result, unless there are some permission issues that are blocking the file. Uninstall and reinstall as Admin is worth a try.
