Both of these classes (bitmap and label) use texture rendering so the problems seems to be coming from there, which makes me think that there is an issue with the 32-bit OpenGL drivers running on that computer.

What graphic card model does this computer have?

I'm having ATI Raedon X1650 series installed.
Find attached screenshot of Call Stack window while debugging. Few traces of User32 and Opengl are hidden there.
I'm also wondering is there a minimum requirement of OpenGl version for chai3d 3.1.1, because at present I'm having opengl 1.1 and due to some reason I cannot able to update it.

CHAI3D 3.X require support for OpenGL 2.1.

It seems that your computer may have received a fresh installation of Windows, which by default will not include any OpenGL drivers, apart for an emulated version (OpenGL 1.1) through DirectX.

I suggest that you try to update the drivers by checking the ATI website.
