Did you remember to reinstall the latest video drivers from your IHV?
I think I’ve seen this error before, but I can’t remember why. If a GLUT file was missing, you’d get a different error (wouldn’t compile, or Windows would stop with a missing dll error), so that’s not it. For whatever reason, GLUT can’t create an OpenGL rendering context with the requested atrributes. Are your parameters to the GLUT init stuff reasonable? Can you post your init code?
