I recently bought a new Mac and I would like to transfer my Lightroom program from my old mac to my new one. It is the newest version of Lightroom, which I downloaded directly from the internet so I do not have a CD or anything like that, also I do not wish to buy it again (If that's at all possible). Is there an easy way to do this? I already have my Lightroom photo library on a separate hard drive, so I just need to transfer the program and nothing else.
Also, is there a way to keep the application running on both computers? One is a laptop and the other is a desktop, so I would like to have it run on both for ease of transportation and traveling.
