Failed to load Revit Grasshopper components

huaxiamengqing1 · October 23, 2019, 1:18am

Hi, I install rhino inside as the constructions, but I get into some errors like below.

I can use Sample 1. But there is no commponents for other Sample.
Actually, Most Grasshopper components failed to load.

An error occured during GHA assembly loading:
Path: C:\Users\Administrator\AppData\Roaming\Autodesk\Revit\Addins\2017\RhinoInside.Revit\RhinoInside.Revit.dll
Exception System.IO.FileLoadException:
Message: The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Rhino inside is a wonderful idea as I thought when I first get learned to use Grashopper. You just realesed it in open souce code. That’s a great thing!

I just checked the Grasshopper.dll referenced.
Version In my Rhino WIP.:
Grasshopper, Version=7.0.19289.23125, Culture=neutral, PublicKeyToken=dda4f5ec2cd80803
Version of the RhinoInside.Revit.dll referenced:
Grasshopper, Version=7.0.19183.10490, Culture=neutral, PublicKeyToken=dda4f5ec2cd80803
I don’t know if it’s that reason.

# Troubleshooting Rhino in Revit

This guide looks at errors that can appear with Rhino.inside Revit.

This address most of the common errors we have seen.  [Please contact us](https://www.rhino3d.com/support) whether any of these options worked or did not work.  We are working to minimize any of these messages.

## Rhino license manager initialization error -200.

Problem: When Rhino.inside loads and this error appears.

Solutions:

This normally appears when there is a conflict between Rhino.inside and one or more Revit plugins that have loaded already.

Just to be sure we are using the same version of Rhino, Grasshopper and RiR, please install the last version of everything.

Rhino 7 WIP: https://www.rhino3d.com/download/rhino/wip
Rhino.Inside Revit: https://www.rhino3d.com/download/rhino.inside-revit/7/wip

Now please test it loads normally from the desktop, not inside Revit.
Also would be helpful to know which version of Revit are you using and if your Windows is also configured in Chinese.

huaxiamengqing1 · October 30, 2019, 1:06am

Thank you Mr Garcia. I use Revit 2017
It seems you paste same url for Rhino 7 WIP–
Yes, My windows configured in Chinese.

kike · October 30, 2019, 4:56pm

Hi,

I’ve updated the Rhino WIP download link on the previous post.
Did you have a chance to test with the last version of everything?
I tested it here and works.

I didn’t test changing the Windows language to Chinese, but Revit and Rhino only.
I see in your screenshot that you have 2017, mine is 2017.2.
I don’t know if this makes the difference but it is worth to try to update.

huaxiamengqing1 · October 31, 2019, 6:24am

Thanks ,I will try it.

@kike

Version: 7.0.19351.11415, 17/12/2019

here is error

how to fix it? your advice will be appreciated

michaldengusiak · December 18, 2019, 4:48pm

I can see file in correct place…hmm

I downloaded code from GitHub rebuild myself but still the same issue

eirannejad · December 18, 2019, 5:20pm

@michaldengusiak
I updated my Rhino WIP to latest and tested. The issue does not appear on mine. Everything loads okay under Revit 2019 and 2020

Would you mind disabling your other Revit and GH addons and load a clean Rhino.Inside? Maybe there is a conflict somewhere

michaldengusiak · December 19, 2019, 9:32am

@eirannejad solved!
Yes, without anything else it worked. I will go one by one to check which one is causing issue. and delete all unwanted files.

Hi Michal,
Did you find the conflicting file?

BR,

michaldengusiak · March 20, 2020, 12:39pm

@rayaanajouz I can confirm that my Rhino.Inside is working perfectly… so no issues any more!

natasha.catunda · November 4, 2020, 9:09am

Hi people,

Just letting you know that with the Rhino.Inside version from 26.09.2020 (and most recent version .msi connection) I was receiving an error load of grasshopper components (revit and others) when I installed the “swarm” addin (from core tt) for Revit.

After removing it everything works fine.

Returning to this five years later with a similar issue:

I’ve had recent issues of not getting Rhino.Inside to load at all, but this is different - Grasshopper boots fine but isn’t loading Revit components within the interface. @Japhy do you think this is a third party add-in issue again?

Japhy · August 19, 2025, 11:52am

Most likely. What is your Rhino.Inside.Revit About info?

If that’s not readily available please post exact Revit version, Rhino version and RiR version.

woodhouse · August 19, 2025, 11:59am

Here it is. I’m working off a new machine, and currently Ideate and Speckle are the only other third-party plugins installed. I have had issues with Speckle causing issues for other plugins in the recent past.

Japhy · August 19, 2025, 3:35pm

Thanks, nothing standing out in the versions.

If the still happens when using this method to start with no other Revit addons we should look at your GH 3rd party plugins as well.

woodhouse · August 20, 2025, 1:06pm

Looks like this strategy worked out in getting GH to load with the Revit components. Thanks for the work-around, and hopefully the normal loading process will resolve itself over the next few days/week.
