The error message you got opening a model in ChimeraX says

ChimeraX requires OpenGL graphics version 3.3.
Your computer graphics driver provided version 2.1
Try updating your graphics driver.

As it says, you have to update your graphics driver to fix the problem. Google "update windows graphics driver" if you don't know how.

[Tom Goddard]

Code should just give clear error message about inadequate OpenGL without traceback. Need to fix that.

[Tom Goddard]

Made OpenGL code not give further errors after reporting that the OpenGL version is not adequate.

Thanks, I updated OpenGL and ChimeraX is working.

I did try the VR mode with our headset and it is amazing!

Thanks again

Best
Phat
