FS#2003 - QCADCAM Crashes when starting up

I am trying to run the QCADCAM v3.23.0 64 bit version under Windows 10 x64. When I start the program, I get the splash screen showing it loading all of the plugins. When it gets to around 67% (Gerber stuff), the program crashes. I get the following exception:

Unhandled exception at 0x00007FFC5F51C706 (MxMGLV64.dll) in qcad.exe: 0xC0000005: Access violation reading location 0×0000000003304318. occurred

I also loaded the 64 bit version of just plain QCAD and it works with no problems.
I also tried loading the 32 bit version of QCADCAM and while it does not crash, it does not display any of the menus, toolbars, or toolboxes. it displays only a black screen with the title bar.

This behaviour more likely indicates an OpenGL problem (OpenGL driver invalid, incompatible or not available).

Please remove the file "plugins/qcadgles3d.dll" and try again. Note that without that plugin, you will not have a 3D preview / simulation widget. To fix the problem, a working OpenGL driver would need to be installed. This can be daunting on Windows and is only really worth the trouble if you need the 3D simulation widget.
