ok, i dont have an anti virus, just windows defender witch i just disabled and tried to uninstal again, same error come up. finished downloading the new driver and i changed the nvdmn file with yours, it goes tru the hardware check but failed after instalation start, for the command prompt i did wat u said but it happens so quickly that i cant see if its succeed or not anyhow i did reeboot and try the drivers again and still the same problem.
