How do I get D3D on my VM? I already installed WineD3D, GuestAdditions, Extension Pack, etc. Whenever I run dxdiag, it says that 3D Acceleration is unavailable. I am running Windows Vista as my Host and Windows 7 as my guest.
Also, I checked the box for enabling 2D Acceleration, but the 3D Acceleration box is grayed out and I can't check it. I've tried everything. Help please?

WineD3D and VBox ? its one or the other not both.

What are you talking about? o.o

Wine3D is integrated in the guest additions.

If 3d in the guest settings is disabled, then you have a problem on the host. Maybe your VGA has not enough capabilities. Or wrong driver on the host.

Yes, but it is also a separate package outside the VBox world and them two don't mix.

He has a Problem on the host. Maybe on the guest too. But without solving first problem it does not work.

I agree. Until the OP can solve the 3d check box problem, it won't really matter what he does in the guest OS.

I can see the potential problems of installing both the guest additions and wined3d in the guest OS.
