not gonna lie this is driving me nuts short version: Quadro Tesla Graphics Driver 295.73 Windows 7/8 64-bit won't install.

Longer version: my home-built tower came with a manufacturer-customized graphics driver... i wanted teh 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 install broken?? i would really 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.
