90-day version doesn’t work properly

Hello dear.
I have installed a 90-day “full” version of Rhino 6 for windows from your site www.rhino3d.com. Unfortunately, I can not enter any of the simplest modeling commands. E.g. according to the manual I draw a circle that appears on the scene/viewport. But then it immediately disappears from the screen. What could be wrong?
Many thanks, Jiri Rubas

Note that the trial version is exactly the same as the commercial version.
Could you run the SystemInfo command in Rhino and paste the result here? That might give us some pointers as to why this is not working on your machine.

Hi, I’m sending the requested information. Thank you for your help. Jiri

Thanks for that, Jiri,
From that information, everything should be working alright.

What happens when you start Rhino in safe mode?
You find that from the menu on the Windows Start Menu:

Your video driver is from 2013 - I would try updating that first and see if that helps…

Thanks for stepping in there, Mitch! I read OpenGL 4.3.0 support and that made my brain read 10-28-2018 on the drivers date…

Yes, @rubas, you will need to try to update your GPU driver!

… have installed the latest version of the NVIDIA driver. It works now! Thank you very much for your help. Jiri
