Cannot enable Aero in Windows 7 RC

[classic44]

I am currently running win 7 release candidate as a virtual pc in virtualbox.
My virtual pc has got 512mb of memory and 128mb of graphics memory, my graphics card is a ati radeon x1650. By some reason i can't enable the aero theme, I click it, but it just remains the Windows 7 basic theme.

What should I do? Please help me

You can't get aero effects running in a virtual environment.

Are you sure?
Cause I'm pretty sure I've seen it somewhere.

It would have to support directX 3d acceleration, i do not know of a virtual environment that provides that.

It seems like Virtualbox supports 3D acceleration

It supports OpenGL acceleration not directX.

You can get Linux's effects to work, cause it uses openGL, Windows uses Direct X
