NVENC not working Error 14

[cyrgh]

Hi. I can't use NVENC for h.264. It returns error 14. My graphics is GT 740M and driver updated to 364.51 which should be fine. Please help!

I'm hitting the same error, with a GTX 660. Clean installation of Mediacoder and driver. But NVENC does not work, always returning the error 014.

On the console:
