How to install OpenCL after installing new Nvidia drivers?

[doctorlexus]

So I've had similar issues before where the default Windows 10 driver works just fine. But as soon as I install the new Nvidia drivers, openCL seems to break.

I had an RTX2070 folding just fine in a box, and I decided to add one of the new RTX2060's. Unfortunately the 2060 is too new for Windows to find a default driver for it. So I had no choice but to download the 417.71 drivers from Nvidia. As soon as they were installed, GPU-Z showed OpenCL checkbox no longer checked.

I went here to try to figure out if I could download and install OpenCL by itself: https://developer.nvidia.com/opencl

But I'm not a developer and I'm confused as to what to download or where to go from here.

Thanks.

Update:

1) Removed FAH and all data.
2) Did the clean option install of new Nvidia drivers
3) Rebooted
4) Reinstalled FAH

All works now.
