    Invalid serial number


      I have a legitimate copy of LR purchased from Adobe. I an re-installing on a new PC and am told that the serial number is invalid. What can I do. It appears as if Adobe do not have a customer support service.

          Did you download the standalone version of Lightroom (also called "perpetual license")? Or did you download the Creative Cloud version of Lightroom?


          Are you installing the same version of Lightroom as the one purchased from Adobe? (In other words if you purchased Lightroom 4, your serial number won't work with Lightroom 5)
