Okay so I bought the disc version of Lightroom 5 around christmas time, and installed it on my PC. I just bought my Macbook Pro and I need it on my laptop-- the only thing is that the computer doesn't have a disk reader. Sooooo I can't install it again (you get to install it on two computers, right?) because of my lack of being able to insert the disk. Just wondering if there is any way I can give my serial number for proof of purchase and be given an online download?
Just go get it yourself. It's available here:
Run the installation package, and then use the serial number that you have already to activate it.
