Rhino 7 Not Starting


Does anyone know why Rhino 7 won’t start? I have a free trial license that is still valid and I have to click multiple times on the Rhino app that sometimes opens.

could be that there is a plug-in or something else that block Rhino…
Try to start in Safe Mode to see if it opens correctly (you can find Safe Mode from Start → Rhino7- > Rhino7 in safe mode).
Another way is to repair Rhino (from windows options, APP, Rhino7 click on Modify and choose Repair from the splash screen that open) or to uninstall and install last version from McNeel site.

Hi Paula - once it starts, please run the SystemInfo command in Rhino and copy/paste the results here.


Now is not even starting :upside_down_face: is there anything I can do?

Okay the Safe Mode opened correctly, is there a way to make the regular Rhino work?

This are the results on Rhino Safe Mode:

At first I would try updating the Nvidia quadro drivers.
I see also this Citrix display adapter that I don’t understand if it’s an usb adapter or is something integrated on the motherboard… could be useful to update this driver too (if it’s an usb adapter, disconnect it).

Hello - if you are not using Citrix, please uninstall it and see how Rhino works then.


also may want to contact tech@mcneel.com and get a newer service release. In special circumstances we can get you service releases that are not quite available to the public yet to see if a newer pre-release version solves your issue.
