Hi - here is the problem. apps are the latest ver. When clicking "edit in photoshop" in Lightroom, LR responds with a message error indicating Photoshop cannot load. So "edit in photoshop" does not work. It is interesting that I have both PS 2020 and PS 2019 in separate folders on my disk. I have tryed to uninstall 2019 but it will not uninstall. Thre are no number codes associated with the error. I have reinstalled both apps. Still the same error. PS 2020 by itself runs fine.
