Error During GHA Assembly Loading in Rhino 8 – ShapeMap 1.0.4

Plug Ins ShapeMap
1

Hi everyone,

I’m encountering an error when trying to load ShapeMap 1.0.4 in Rhino 8. The error message is as follows:

An error occurred during GHA assembly loading:
  Path: C:\Users\[USERNAME]\AppData\Roaming\McNeel\Rhinoceros\packages\8.0\ShapeMap\1.0.4\ShapeMap1.0.gha
  Exception System.IO.FileNotFoundException: 
  Message: Could not load file or assembly 'System.Runtime, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

It looks like System.Runtime v7.0.0.0 is missing or not being found. I’ve tried reinstalling the ShapeMap plugin, but the issue persists.
I have already installed .NET 7 SDK and .NET 7 Windows Desktop Runtime, but the issue still occurs.

Does anyone know how to resolve this issue? Any insights or suggestions would be greatly appreciated.

Thanks in advance!

Hey everyone,

In response to my own post, I recently encountered an issue where ShapeMap wouldn’t start in Rhino 8, and after some troubleshooting, I managed to fix it.
If you’re facing the same problem, here’s how I resolved it.

1. Install .NET SDK 7.0

2. Set Rhino’s .NET Runtime to NetCore

  • Open Rhino and run the following command in the command line:
SetDotNetRuntime
  • Choose “NETCore” as the Runtime.

3. Restart Rhino

  • After making these changes, ShapeMap successfully started in Rhino, and I was able to generate Grasshopper definitions as expected.

If anyone else runs into this problem, hopefully, this fix works for you too!

Let me know if you have any questions.
