GPU missing error

(moderation:
I have just upgraded to latest windows 10 1809 version. Use NVIDIA GeForce GTX 970 (4095MB) driver: 397.64. This is working perfectly for the Seti@home GPU tasks but fails for Einstein tasks. All the Einstein CPU tasks are still working ok. I have later versions of the Nvidia drivers but the last time I tried one of the newer ones both Seti and Einstein GPU tasks failed to run. Latest driver is 417.71, is it worthwhile trying that?
Boinc log file shows:-

Where did you source your driver download?
"App version needs OpenCL but GPU doesn't support it" usually means a limited-feature driver distributed by Microsoft, and can be cured by running the full-feature driver downloaded direct from NVidia - even if the version numbers are the same.
You might need to choose the 'clean install' option in the NVidia driver installer.

I suggest you install 417.71 unless you have specific credible information of a problem for your configuration.
As Richard mentioned, I suggest clicking the clean install option on the Nvidia installer.
I have two of my three Einstein GPU hosts recently upgraded to Windows 10 1809, and neither lost Einstein capability during that upgrade. However plenty of Einstein users have reported losing BOINC GPU capability during Windows upgrades. I don't know what influences how that turns out.

Thanks for comments. Just done a clean install of 417.71 and everything now back to normal!!
A previous windows update 1803 version messed up the video driver but both Seti and einstein were affected then.
Just need to see if I can amalgamate my Einstein accounts as this one was for my Android tablet.

Yes, it's the big six-monthly updates that you have to watch out for - the next ones will probably be 1903 in March and 1909 in September.
In the early days of Windows 10, the Microsoft drivers didn't support any sort of distributed computing: recent ones have supported the CUDA language subsystem (so SETI should work), but don't support the OpenCL subsystem used here - as your message log showed.
It's possible that if you have a working OpenCL environment, it might survive the update, but I'd always check afterwards just in case. If you have an Intel GPU in the same system, you'll get OpenCL for that, and it'll work for NVidia GPUs as well: but failing that, you'll need to go down the NVidia download route.
