DaVinci Resolve 17b2 will not start

Tried reading all the forums on this problem but cannot get a solution to work. Installed Davinci Resolve 17b2 and installed opencl-nvidia455 and does not detect opencl. In Davinci Resolve Configuration shows my gtx770 with opencl and it’s greyed out.
Any ideas how to make it work?

Interestingly I have another computer which is 5930k with Nvidia GTX970 and it works fine. Exactly the same software setup.
