Revit cannot run the external command "Grasshopper"

Rhino.Inside Revit

After updating Rhino.Inside to version:
RhinoInside.Revit_0.7.7815.25113
I keep getting this error when I am trying to start Grasshopper from Revit 2020.2 (no error is being thrown in Revit 2021.1.2)

Thanks for getting back to me Ehsan, it was ComputeHub addon that was conflicting with RhinoInside.Revit

Glad you found the conflict. What does ComputeHub do?

Hi @tatjana.somova,

There is a new release (v0.8) at ‘Daily Channel’ that hope to fix this problem.
May you confirm us it is fixed on your side?

Thanks.

Hi Japhy, thanks for the link - I don’t see this issue under the known issues or troubleshooting guide. Is there a solution for this? I am getting the same problem in Revit 2019.2 with the latest Rhino.Inside

Hi Maxime,

Can you provide your About info?

These are typically Revit Addin conflicts, but there was a similar unresolved report yesterday.

I’m not seeing an issue currently.

Hi Japhy

I’ve saved a message log of how I encounter this error, screenshot below:

I didn’t send any error report though because it does not give me the option to do so

RhinoAssemblyResolveLog.txt (554 Bytes)

Thanks,

Maxime

I am also getting this error on Revit 2019.2

I’ve disabled all plugins, Rhino Inside will start but Grasshopper will not.

Try opening Rhino and initiating GrasshopperLoadOneByOne in the Rhino command line.

I’ll have access to R2019 tomorrow and will test on my end.

Most plugins loaded one by one without any problem, but I got this error:

Priority: GhpyLoader
{
The Rhino IronPython plug-in could not be loaded. It was either disabled, or it cannot load on your system.
ApplicationException
}

After dismissing it, GH opened!
