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:

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.

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](https://www.rhino3d.com/download/rhino/wip)  
Rhino.Inside Revit: [https://www.rhino3d.com/download/rhino.inside-revit/7/wip](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.

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.

 ![image](https://global.discourse-cdn.com/mcneel/uploads/default/original/3X/1/9/196430f758cdd6c898bc0d02078f74f208cd2886.png)

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.

@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

@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.

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

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:

 ![image](https://global.discourse-cdn.com/mcneel/uploads/default/original/4X/e/a/5/ea5898ffa4d9468c54975bf20639664626e89929.png)

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?

Most likely. What is your Rhino.Inside.Revit [About](https://discourse.mcneel.com/t/help-us-help-you-rhino-inside-revit-edition/170291/5) info?

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

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.

If the still happens when using [this method](https://discourse.mcneel.com/t/help-us-help-you-rhino-inside-revit-edition/170291/7) to start with no other Revit addons we should look at your GH 3rd party plugins as well.

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.
