I installed standalone LR6 and now cannot open 5.7 when vs.6 is running. In the past, I have kept the perfectly good previous versions so switching between two sets Help! of photo sessions is just a click away. Now, with LR6 running, all I get is a yellow blinking icon when I try to open 5.7. So, I have 5.7 but can't run it while 6 is open or the other way around. Also, files opened in one of these versions would also be in the other one, meaning if I closed 5.7, opening 6 would show the same files and vice versa. I checked shortcut paths and those are correct. Help! OS is Win 8.1, unfortunately stuck with it for a while.
