I suscribe to CC and I'm trying to upgrade my LR5 to LR6. It downloads but the program will not open. I have uninstalled and reloaded three times. LR6 program will not open. LR5 continues to open as usual.My version of LR5 was a stand alone version I had before I suscribed to CC.
had the same problem. Try signing out from creative cloud and then signing in again.
