I cannot seem to get the NVIDIA 304.79 drivers to install under Windows 8 on my rMBP. During installation, the core graphics driver is just listed as "Failed" and the installation stops. I am using the English (US) version of the driver and I have modified the INF file correctly. I have tried to perform a clean installation of NVIDIA drivers (under custom installation). I have tried completely removing the existing NVIDIA drivers. Anyone else encountered this issue?
