Human UI "Method not found" Wpf.Toolkit

Hello all,

I recently discovered Human UI and its an awesome piece of work, but I cant make it work for me for some reason.

When I use the "value listener" and "create color picker" nodes I get "method not found" error, something related to the Wpf.toolkit (images attached).

Unfortunately I have no clue what that means of how I fix that. Did my unblock/reinstall ritual, to no avail. The funny thing is that my colleagues can install and use these nodes with no issue whatsoever.

As the "value listener" is arguably the most important node in the whole pack, I am left without Human UI, and no one locally has any ideas how to fix it.

I would be grateful for any suggestion.

Seems like a missing/failed DLL reference. Do you have XCeed.Wpf.Toolkit.dll (attached) in your HumanUI folder? Make sure it's unblocked. If that fails - watch your Rhino command line when starting up, see if any loading errors occur.

Also for future, Human UI-related questions will be answered quicker if posted to the Human UI grasshopper group.

Hi Andrew, thanks for your reply and the info. Sorry I couldn't answer sooner. I guess there is no point in double posting now, hopefully this can be resolver here.

The XCeed file is there and is unblocked. The command line doesnt seem to be showing any errors.

Is there anything else I can do?

I have a couple more ideas:

1. Please double-check the rhino command line at Grasshopper launch - you may have to expand the window to see everything. I would be very surprised if you were having an issue w this DLL and it wasn't reported there.

2. double-check your load setting under the "GrasshopperDeveloperSettings" command in Rhino. Whatever this is set to now, try switching it to the opposite and then relaunching grasshopper.

3. Try the attached python script (you'll need the python script component installed, also attached just in case). Change the panel to point to the location of your Xceed.Wpf.Toolkit file, and then let me know if any errors come out of the python component.

4. Double check your Grasshopper version. You should have 0.9.0076

Let me know the results of those checks - if we get some information back it helps me figure out how to solve your problem.

1. Loading Grasshopper does not prompt any error messages in rhino. Nothing but the usual "Command:Grasshopper" shows up.

2. Unchecking the tickbox worked! The HUI nodes now load as expected. But now Im getting a bunch of errors while loading GH looking like this:

"An error occured during GHA assembly loading:
Path: C:\Users\dkorolen\AppData\Roaming\Grasshopper\Libraries\SpeckleUploader.gha
Exception System.IO.FileLoadException:
Message: Could not load file or assembly 'file:///C:\Users\dkorolen\AppData\Roaming\Grasshopper\Libraries\SpeckleUploader.gha' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)"

It seems to only have broken the Mosquito plugin. No biggie, didnt use it much anyway.

Thank you for the solution Andrew!

If you need to get those other plugins working again, you can set overrides for the application-level load setting in grasshopper preferences. Glad we could get to the bottom of the issue!!

Hey Dmitri - just curious - were you by any chance using the Rhino 6 beta? I had this same error when I tried to use Human UI in Rhino 6.

No, I'm actually using Rhino 5 (5.12.50810.13095).
