8800 GTS (v2) and CUDA 174.55 installation

Hi,

I have installed the latest WHQL drivers (175.19) previously (works perfectly). I decided to use Folding@Home for my GPU but I can’t install the latest CUDA drivers available (174.55).

I think the installer don’t wants to overwrite the current drivers or even just install the drivers.

I tried to clean up the 175.19 drivers and then install the CUDA drivers but it doesn’t work but I can’t access to the control panel and the drivers don’t work.

Is there a way to install the CUDA drivers ?
