According to Creative Cloud, Lightroom is installed on my mac, but the app is not in the Apps folder.
Therefore nothing happens when I try to open Lightroom via Creative Cloud. I get no error messages and I have tried to uninstall and reinstall Lightroom several times - deleting all settings and plugins when uninstalling - but with no sucsess.
When installing the prosess takes about 2 seconds in Creative Cloud - which can not be right.
Yesterday I responded to a similiar query where the app was not installed in the Applications folder but instead landed in the Home directory. Can you find the app using Spotlight? If yes then launch it and once it launches Cmd + click on the app icon shown on the dock, this will open the folder where the application is installed.
Alternatively you could try a fresh install by first uninstalling using the Creative Cloud Cleaner Tool. Details mentioned here.
