I just bought the Lightroom download on amazon and successfully installed it on my Mac (I see the LR symbol on my desktop). How do I actually start the program? When I click on the LR symbol on the desktop, all I get is the read me file and the package symbol. It doesn't ask me to enter the serial key.
Kind Regards from Munich
You may have only expanded the download file to the desktop folder.
Open or run the 'package' file which may continue with the installation.
Then when fully installed and run for the first time it will request the serial key.
