Resolve 15b3 won't start after latest Windows upgrade

This is probably not a Resolve issue per se, but after today's big Windows update Resolve 15b3 didn't start, giving me all kinds of OpenCL related error messages.
After doing a reinstall Resolve came back.

It's probably not the way it should be, but definitely something worth paying attention to IMO.

I had what appears to be the same issue with Windows 1803. See viewtopic.php?f=32&t=74018
Like you, rolling back to 1709 seems to have fixed the problem & now Studio 15b3 works.

The major Windows updates, like 1803, are full system installs and technically not updates. In this Windows has a tendency to delete, or not keep, the installed OpenCL.dll from the video driver.

Reinstall your video driver and you should be fine. I state this since you commented about OpenCL errors and that is what happened to me as well. Driver re-install corrected the Windows update issue.
