I have a previously installed version of lightroom 5 that I had installed prior to purchasing the creative cloud. This whole time I thought I was updating through cc but apparently I was not. Now I am trying to merge over to lr cc but don't know how because the previously installed LR 5 install is taking precedence and not allowing the cc to open. I am afraid to uninstall the 5 because I don't want to lose my catalog! Help!
