OpenGL framebuffer extension not supported

[AloAlo]

Hi,
I get the message:

openGL compatibility test failed
reason: frame buffer extension not supported
try to update the driver of your graphic unit

the guest is a Windows7 on a Macbook Pro

I googled quiet a lot, but didn't find an answer yet.
Any idea ?

Did you install the Guest Additions? Did you enable 3D acceleration?

Hello.
Have the same problem.

Yes I enabled 3d acceleration and all guest additions inc. full 3d support had been installed.
