Why can I not instal Lightroom 6 onto my Mac Book Pro?
My friend purchased Adobe Photoshop Lightroom 6 as a gift. I have tried to install it on my Mac. Had problems initially to get the installer to work, then when it finally worked when I entered the serial number it says not genuine product but it is. It was bought from a reputable shop, it is in the branded box with 'Genuine' Adobe hologram sticker and the disc is original (you can tell it's not a counterfeit). I am running on Yosemite. Any help would be greatly appreciated. My friend lives in New Jersey and I am in the UK......could that have any impact? Any help would be greatly appreciated.
