I have an up-to-date version (7.3.1) of LR Classic. I have some of the presets that came with the updated LR (Artistic, B&W, Modern and Vintage); however I do NOT have the profiles that were with the older versions, which are supposed to be in the Profile Browser, i.e. Adobe RAW, Color Matching, and Legacy.
A screen shot of my Profile Browser is attached. How do I get the three missing profiles?
