Hello, I downloaded lightroom 5 as a testversion for my mac (system 10.7.4). As I want to work with the program I am looking for a way to get a license key. With adobe it seems that it is not possible to get one as they only features the very new version of the program which is number 6. As I do not want to upgrade my system I would really appreciate to work with lightroom 5. Can somebody help?
You'd have to see if third party resellers (such as Amazon, B&H, Adorama) can sell you Lightroom 5.
Another issue that you will encounter is that there are no more updates to Lightroom 5. That means that if your camera is not supported by Lightroom 5 now then it never will be. It will be necessary for you to use the DNG converter to create DNG copies of your raw files.
