Hello,

I am trying to create an application with Core3D, however if I add the component to my VS project and/or start the [VB.net](http://VB.net) Core3D, it crashes. If I look at the event viewer I see the following:

Have you seen this beforehand?

It is running Win 7 - win 32.

Any ideas would be appreciated.

Thanks.

Raff

Hi @Amicelli,

by Core3d you mean the 3D Viewer ActiveX control? If yes, do you have a graphics driver installed supporting OpenGL?

Which version of OpenGL does my graphics card need to support?

The CVCore3DViewer.ocx makes use of [VTK 7.1.1](https://www.vtk.org/) to do its job. On Windows we use the `vtkOpenGL2Renderer` class which - despite its name - requires OpenGL 3.2 (see discussion [here](http://vtk.1045678.n5.nabble.com/vtk-7-1-openGL-2-0-crash-td5744014.html) if you want more detail).

OpenGL is normally **not** usable on virtualized machines (VMWare, VirtualBox and the likes) and is questionable through some remote desktop environments.

@illusive, thank you for the clarification.
