I used to run it on a laptop, but switch and now this stupid thing keeps "installing updates" but fails. Anyways it ran just fine for me.

I have a DEll Inspiron 1525 and I play POTCO on it with no problems. Sukael is right about the support about the video card. Mine has an NVIDIA 8600 GS Video Card and requires to update the drivers from DELL directly and not from NVIDIA.
