i have installed the latest human ui version from food for rhino
i am using rhino 5.14
grasshopper 0.9.0
the human ui control window comes in blank (black in color) with no button or text being displayed
even for the example files.
i did a clean install of rhino and grasshopper and all my components once and still there is no improvement
that’s weird, never seen that before. I have no idea how to even begin troubleshooting that. Are you using some kind of odd windows setup like virtualization running on a mac or anything?
thank you for your quick response,
no i am not using any virtualization for running rhino (rhino is running on my windows 10 Home Single Language, i7700hq 64 bit)
though i have a virtual box instance for running open foam
i closed it and restarted my computer i am still getting a black window
very strange. When you launch grasshopper from the rhino command line, do any errors show in the command line? (you might have to expand it to see any)
i get these errors in a window, they are related to a charting plugin i installed earlier.
i will try removing all the other plugins that i dont currently need and try it again.

i removed the plugin that was causing the errors it was the AVIARY plugin (by neoarchaic)
now while launching grasshopper i get no errors
still only a black window shows up while launching human ui
i am currently doing a clean rhino and grasshopper install where i will not install any other plugin other that human ui, to check to see if the problem is because of a clash with another plugin
ok so i did a clean install with rhino, grasshopper, human ui, honeybee,metahopper and python. but still i get a black screen for the control window for the human ui interface.
i am also getting an error
this script that i have to use uses human ui for all then simulation inputs and visualization for the work that i have to do by tomorrow i will currently have to remove all the human ui components and enter all the data manually. (this will be quite cumbersome).
HelixToolkit.wpf should get installed along with human UI - I don’t know why it would fail to load.
you should have these files in your HumanUI install folder (%appdata%\Grasshopper\Libraries\HumanUI):
Some googling (https://www.codeproject.com/Questions/809219/Windows-tablet-renders-wpf-window-as-black-screen) shows that sometimes this issue is related to hardware acceleration - you might try disabling that?
i dont still dont know what was causing the problem
but i uninstalled all the softwares from my pc that i didnt need, and did multiple windows defender scans, found a lot of trojans, removed them. uninstalled rhino 5, switched to rhino 6 and everything is working perfectly now.
Hi Andrew, Gokul,
I am having the same issue of black screen. Upon searching for solution I stumbled upon this conversation. Did you manage to resolve the issue? I am using Rhino 6 on Windows 10.
I’d try uninstalling all your grasshopper plugins and re-installing human UI — if that solves it, it’s a plug-in conflict, and you can try adding back the other plug-ins 1 by 1 until you find the culprit.
I did not reinstall the Human UI plugin but deleted many unused plugins, which made it work. Not sure which one it was the culprit.
Thanks for your help.
If you can find the time to do this it would probably help some other users going forward. 
If you inspect the files included with the other plugins, look for any DLLs that seem to be UI related, or mention WPF — (eg the HelixToolkit plugin mentioned above). Anything that launches its own UI is more likely to have a conflict with Human UI.
