In Launchpad I see the following apps:
Adobe Photoshop CC 2015
Adobe Photoshop Lightroom 5
I only want Adobe Lightroom CC 2015 (which shows in Adobe CC desktop and installs fine from there).
Should I only delete Adobe Lightroom in Launchpad?
Is Adobe Photoshop Lightroom 5 actually Adobe Lightroom cc 2015 ?
They are all different versions of Lightroom so you can uninstall the versions you do need. Do this via the uninstallers in the Adobe foldear in applications.
Lightroom 5 is a different version to 2015
