I’m trying to run a simple vtk example on a Windows 2019 machine.  
I’ve got elastic graphics for this machine.  
I’m getting following error while running the VTK example on this machine.

GLEW could not be initialized: Missing GL version

Is there any fix for this error?

thanks,

Could you install [glview](https://www.realtech-vr.com/home/glview) and share the output?  
This could be an aws driver misconfiguration since elastic gpu forwards all gl calls to a remote gpu.

If all looks good, you might want to get in touch with AWS support.
