K20c Failed with error code 10 on Windows 7

I’ve just insert a K20c on my workstation along with an NVS-510 card. After installing CUDA-7-5 and reboot. The NVS-510 works fine. However, Windows cannot get my Tesla K20c works. My driver version is 10.18.13.5390. Anyone get idea on this issue. Thank you for reading.

I have similar issue, I have downloaded the 354.13 driver for win10 but I can not install it, it gives an error that the OS is not supported. Have you found a solution?

Not yet. My version is 10.18.13.5390 (353.90).
