I bought a Mac Desktop and I want to move my lightroom 4 from my lap top to my desktop. I have the serial number, however I have not found a way to start lightroom 4 on the new computer. I am currently using lightroom 5 as a trial. This trial will run out soon and I need to keep using this program.
This forum helps a little. except I need to upload the same version of light room that my serial number will accept. How do I get Lightroom 4 version?
