Longer version: my office PC came with a manufacturer-customized graphics driver. I wanted the newer one from NVIDIA directly. Every installer I try says its incompatible with my Windows. Is the laptop maker locking this down, or is my Windows insatll broken? I would realy prefer not to reinstall Windows just to update one driver. If there is a way to check what teh installer is actually comparing, I would love to know it.
