Graphics Processor problems

I would be grateful for advice about the resolution of the error message 'cannot find OpenCL compatible GPU'.
I have been using Davinci successfully for some time on one machine with an Intel (R) HD Graphics 630 and have now bought a new machine with Intel i7 processor and 16GB RAM, 256 SDD and iTB HD and it has the same model GPU as my other machine but it will not run Davinci, giving the above error message. I have updated all my Intel drivers. I would be most grateful for help.

What specific version of Resolve have you installed?

Version 16. I also tried the beta 17 which also gave me a GPU error although this one did not mention Open CL.
