Hi Rainer, yes normally moi will work fine on a laptop as long as it has some kind of 3D enabled video card on it, which is usually present unless it is a pretty old one.

Windows 7 already comes with Direct3D 9 installed so you shouldn't need to install it.

It could be a driver problem though, your best bet is to go to the ATI web site and download the newest drivers for your particular video card and install those and see if that solves things.

Also check your display settings, do you possibly have the desktop set to display in 16-bit color or something like that? If so try changing the desktop to display in full 32-bit color.
