longer version: my office PC came with a manufacturer-customized graphics driver. i wanted teh newer one from AMD directly. every installer i try says it's incompatible with my Windows. is the laptop maker locking this down, or is my Windows install 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.
