Enhance Details option does not show up in my copy of LR Classic CC 8.0 [was 8.2] Build 1193777

Wrong version. Yours 8.0. You need 8.2 and then something to get that feature to work.

That build number matches up to Lightroom Classic version 8.0 not 8.2.

As dj_paige asked what is your OS version?

The OS version may be preventing the Lightroom upgrade and the new enhanced details needs the newest version of OS as well to function.

Copy/Paste the first 10 lines from "system info" in the Lightroom Help menu in your next reply and that will give everyone the needed info.

Do you mean that the menu isn't there, or that it doesn't work? Enhance Details only works on RAW images. It does not work on jpeg or tiff images, and it does not work on HDR or Panorama DNG images.

Please tell us the exact version NUMBER of your operating system. Do not use words like "latest" or "current", we need the version NUMBER.
