I´m using Lightroom 5. Recently I tried the CC for some days. Now my Lightroom 5 can´t open my Cataloges anymore for it is now said, that the Version is too old. Is there a way to open my Cataloges with Lightroom 5 again?
Moved out of the Forum Lounge (not for technical support) and to the Creative Cloud Download & Install forum. Perhaps someone there will have come across a similar issue with older Adobe programs after installing CC.
Any catalogs used in Lightroom CC cannot be used in Lightroom 5. That's just the way it is.
You have to find your Lightroom 5 catalog file, it's still there somewhere on your hard disk, it hasn't moved or been changed, and open that. (You can use your operating system's search feature to search for all .LRCAT files, one of those is the one you want)
