That doesn't sound right. To my knowledge, there is no interaction between the CC programs and Lightroom 5 that would remove the older program. Are you certain that it isn't in your applications folder? I know I'm not much help, but I'm a Windows user and have no experience using the Mac.
Thanks for responding, Jim. I know... that doesn't sound right but that's exactly what happened. I searched my applications folder - and my file system - it was gone.
I hunted down my install disks and re-installed Lightroom 5, then upgraded to the latest version (or should I say last version - it's no longer being updated.) So far, so good.
I have previous versions of CS on that computer (CS6, CS5) that I keep around just in case CC has a spasm and won't allow me to load the apps (which I am glad for now given the spur-of-the-moment forced upgrade. If I was on a deadline and couldn't wait for the LOOOONG upgrade process to complete, I would have had to use one of the previous versions to get my work done). The previous CS versions were unaffected by the CC upgrade - they're still there. I checked my account and noted that I had registered them, but my Lightroom registration wasn't in there. I probably forgot at the time of purchase. (I've registered my serial number now. Hopefully, that keeps this from happening again).
If that was the cause, then that's a really bad policy. I'm a paid owner of that software, I have the invoice to prove it. I would have been really ticked off if I couldn't find my install disks and was left Lightroom-less.
Hmmm, was that the plan... to force me to pay for another subscription for Lightroom CC?
That is a strange one. I wish I had an answer for you but I don't.
