Lightroom 5 disappears with CC Install

Question

It would appear that my licensed copy of Lightroom 5, which I downloaded online, has disappeared with the install of CC.  In my dock I have a question mark on the Lightroom icon.  And installing from CC asks for a license number.  Is there a way to retrieve my license?

Answer 1

CC products are licensed when you are logged into CC and not when you’re not so if you are installing the CC version of LR then you need to be logged into CC when you are doing it.  I am talking about being logged into the CC Desktop app running locally on your computer, not just logged into the creative.adobe.com site when you download it.
If you mean that you already had LR 5 on your computer prior to installing CC, then keep in mind that the LR 5-CC is different than the LR 5 non-CC but only in that they are licensed differently, so the program, itself, must be uninstalled and a new version installed when you switch from non-CC LR to CC-LR.
When I got the PS+LR CC bundle a few months back, my LR 5-CC wouldn’t even show up in the CC listing prior to my uninstalling the non-CC LR and then explicitly logging out and back into the CC-Desktop app to get it to rescan what local software I had and compare it to what I was licensed to use through CC.
After I uninstalled the LR 5 on-CC, and logged out and into CC-Desktop, LR CC showed up in my CC Desktop as a valid app to install, and when I did that, the serial number as filled in automatically, because I was logged into CC at the time I did the install.
It’s not clear to me what LR your shortcut was to and where you’re installing the new one from.  I am on Windows, so the Mac versions may work a little different, and Adobe may have changed how CC works a little so it may allow the LR-CC version to install over the top of the LR non-CC version without uninstalling the non-CC version.
A question:  are you seeing LR-CC show up in your list of available or installed apps in the CC-Desktop app running locally on your computer or not?
