Title: KUKA|prc User Interface Error
Post by: utsoa on March 24, 2025, 07:51:21 PM
Hi. Looking for some guidance with resolving a "KUKA|prc User Interface Error" after installing KUKA prc for Rhino 8.x. I've searched through other topics on the forum and found one similar the .NET but not quite this one. Thanks.

Hello,
That points to a missing Oxyplot library. Did you use the regular installer or copy files manually?
You could also try to search for Oxyplot in your component library, maybe another component is also using that library and GH is getting confused.

Best,
Johannes

Hi,
Looking at a few directories for the Oxyplot library:
Oxyplot is missing from here:
"C:\Program Files\Rhino 8\Plug-ins\Grasshopper\Components"
and
Oxyplot does exist here:
"C:\Users\%user%\AppData\Roaming\Grasshopper\Libraries"

I reinstalled KUKAprc using the "KUKAprcGH_20240325.exe" installer. I'm able to see my KUKA in Rhino, and able to slide the slider in Grasshopper to see the bot move as expected. Selecting the KUKA|prc Settings button in Grasshopper shows the "KUKA|prc User Interface Error" window.

Hello,
Sorry for the slight delay in getting back to you.
OxyPlot should be in "C:\Users\%user%\AppData\Roaming\Grasshopper\Libraries\KUKAprcGH" and not directly in the Libraries folder.
Also check via the PackageManager command in Rhino if KUKA|prc is also installed via that, so that it's around twice.
Best,
Johannes
