I downloaded Lr and trialed the product for a month. I then signed up for the monthly fee which included Ps. I can access Ps but when I go to Lr it asks me for a serial number which has not been supplied. On the help pages it states "You can convert your trial to a Creative Cloud complete or single-app membership by purchasing on the Creative Cloud website. After you purchase your membership, your desktop product trial will automatically be licensed upon relaunch". I have closed down my Mac overnight but on opening up it still asks me for a serial number so I cannot open Lr? Help!
If you downloaded the standalone trial version of Lightroom, it will be necessary for you to uninstall that version. Then you will be able to install Lightroom through the creative cloud application manager. After you install Lightroom that way, just double-click on the catalog that you have already started.
I have now uninstall Lr but when I click the CC icon the dropdown box tells me that it Lr is up to date. What's going on?
After having uninstalled Lightroom I would try shutting down your computer. Restart and open the Adobe Creative Cloud Application Manager and it should offer Lightroom CC as available for download. Proceed with the download and installation and the license should complete automatically.
