I'm downloading to my MacBook Air with OS10.9.5. The request for serial number is the final step, but is blocked by the serial # demand. I took a 1-year subscription, don't recall any serial #, but the
blockage seems impossible to get rid of. Any ideas what to do? If there's a serial # how do I find it? Thanks
If you are being prompted for a serial number then you have downloaded the standalone licensed Lightroom. It won't work with the creative cloud. You will have to uninstall that version, and then install Lightroom from the creative application manager.
