When I try to open Lightroom 5 on my computer, I get a box that says Confirm at top then in box "The lightroom catalog named Lightroom 5 catalog" cannot be opened because another application already has it opened. It will not let me choose or create another catalog. I have unistalled it and re-installed and it still says same thing
In the same folder as your Lightroom catalog is a file whose name ends with .lock
Delete this .lock file
Do not delete anything else.
Thank you. I will try that now.
