A few months ago I opted for a free trial of Lightroom. I liked it but didn't sign up because I was using Aperture on my iMac. Then Apple decided to drop Aperture, so recently I decided to move to Lightroom. I went to B&H and bought Lightroom 5.3 (hard copy) and attempted to install it on my computer. The installation guide says it's installed, but I can't find it in my Applications folder and I can't find a way to open it. What am I doing wrong?
