Question

I am trying to license my recent download of Lightroom 5 onto my recently purchased Macbook with the serial number of the disk I purchased last year for my Windows PC (an upgrade from Lightroom 4).  I receive an error "The serial number you entered is invalid".  Why does CC not recognize this as a valid serial number?

Soyouca how did you install Photoshop Lightroom? Please uninstall the current installation using the uninstaller located in Applications/Utilities/Adobe Installers.

Once Photoshop Lightroom is removed please download a fresh copy of the installation files from Adobe - Lightroom : For Macintosh. The update contains the full installer so please download the latest version of Photoshop Lightroom 5.

You may be asked to enter your serial number for Photoshop Lightroom 4. You can find information on how to locate the serial numbers under your account at Find your serial number quickly - http://helpx.adobe.com/x-productkb/global/find-serial-number.html.
