Jswan not showing up

Hi @andheum

For one of our students I wanted to install Jswan. We tried using the packagemanager and via food4rhino (deblocking etc.) But somehow it does not show up in grasshopper. What could be the issue here. (rhino 7)

Could be a conflict with another plug-in, likely another older newtonsoft.json.dll floating around

Hi @andheum,

We just installed Rhino today. I could not find a newtonsoft.json.dll anywhere in the rhino folders.


But still no succes:

Does it fail to show up in the toolbar, or does it just fail to load those specific components? Can you send me the .gh file you’re trying to open?

It does fail to show up in the toolbar.

Hi @andheum,

Is there a way to find out why jswan is not appearing on this particular computer?
The only other pluginn which is installed is Human and REVIT is installed on this computer.

do any errors show up in the rhino command line when grasshopper loads?

I was having a similar issue with Jswan and for me it was related to the “newtonsoft.json.dll” file Andrew just mentioned above.

When you open Rhino. Do you get the following message on the command window ?

An error occured during GHA assembly loading:
  Path: C:\Users\Leland\AppData\Roaming\Grasshopper\Libraries\jswan_0.gha
  Exception System.IO.FileNotFoundException: 
  Message: Could not load file or assembly 'Newtonsoft.Json, Version=12.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.

If you do, my response to lelandjobson might do the trick: Jswan / newtonsoft · Issue #12 · andrewheumann/jSwan · GitHub

Hope that helps

Tanks @andheum and @Alebrew !
That was the case.
