OpenGL graphics error while starting up + glGenVertexArrays error

[elvis.marti@…]

The following bug report has been submitted:
Platform:        Windows-7-6.1.7601-SP1
ChimeraX Version: 0.8 (2018-11-30)
Description
(Describe the actions that caused this problem to occur here)

Log:
UCSF ChimeraX version: 0.8 (2018-11-30)  

There was an OpenGL graphics error while starting up. This is usually a
problem with the system graphics driver, and the only way to remedy it is to
update the graphics driver. ChimeraX will probably not function correctly with
the current graphics driver.

As the ChimeraX error said, update your graphics driver if possible:

"There was an OpenGL graphics error while starting up. This is usually a
problem with the system graphics driver, and the only way to remedy it is to
update the graphics driver. ChimeraX will probably not function correctly with
the current graphics driver."

Your graphics driver is from 2013. We recommend on the ChimeraX download page that you use a computer no older than 3-years old because we use modern graphics capabilities. For older computers you should use our older program Chimera. Also ChimeraX is compiled for Windows 10 and you are running Windows 7. While it may work on Windows 7 we have not tested that.
