(SOLVED)Help! Can't load Xnurbs in Rhino winV6. Was ok just yesterday


From today, can’t load Xnurbs in rhino.

Tried reinstalling the plugin and says successful, but just won’t load after reloading app.

Rebooting PC also not working.

Also checked to see if virtual machine related things are off, and there set off.
Hyper-V and Bios related as well.
Still not loading.

There was a Windows update that happened last night, might be that…
Any Help is appreciated!!!
(contacting xnurbs support via mail as well.)

Currently trying to “fix” Rhino V6 with installer → Still same, not loading.

Something to check: The video drivers are somewhat old. Are they versions that Windows update installed over newer ones that you had been using before the Win update?

I’ll see if updating device driver changes things.
Thanks for the info.

Updated driver, still not loading…

Solved by below steps:

Clicked the Install Button in Plugin settings in rhino and followed below steps.

Hi Toshiaki, I had a time once similar to what you are describing. It was a firewall blocking the plug in from loading. It loaded into the computer too a certain point then stopped and wouldn’t load into Rhino. It took it to our IT guy and he disabled something to let it load into the computer. —-Mark
Sorry didn’t e you had it solved.
