LR CC Saved Presets- How to load in LR Classic ?

Lightroom cloud no longer stores the presets locally, it only stores them in the cloud. You can export presets however. Right-click on a preset name and choose 'Export'. That will export the preset as .xmp file, which you can then import in Lightroom Classic using 'Import preset'.

TBMK: (and sort of guessing at the workflow)

If you only have ever run Lightroom-Desktop (Cloud Version v3.2.1) on your computer then-

The user develop presets would be located in :

In Windows:  C:\Users\username\AppData\Roaming\Adobe\Lightroom CC\Develop Presets\User Presets

On a Mac: /Users/[user name]/Library/Application Support/Adobe/Lightroom/[preset or template folder]

(Default develop presets are not user accessible however.)

Lightroom-Classic would store Presets here-

Windows—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ Camera Raw \ Settings

Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / Settings

I suggest that you would copy the Presets from the Lr-Desktop (Cloud) folders to the Lr-Classic folder location.

Or use the Lr-Classic Preset 'Import' function [+] to import them to Classic from their Lr-Desktop locations.
