Good day, I bought lightroom 6 a few years ago online (install CD) and i have lost the box it came in that had the serial number on it. I still have the install CD and need to install the program on my new laptop but dont know what the serial number is. I have looked in all files and folders on my old laptop and cant find any serial number. I never registered on adobe which i regret. Any advise on how to obtain my serial number?
