1. Re: lightroom won't open - I get an error message....is open in another application.....It isn't and I can't progress from there. It allows me to open a different catalogue such as April 2015 but that has only 2 photo's in it ? Any suggestions ?
JimHess Mar 14, 2015 5:12 PM (in response to mcmre1)Depending on your operating system, use Windows Explorer or Finder to open the folder containing your catalog. In that folder you will find a file with the same name as your catalog, but with the .lock extension. That file needs to be deleted, and then you will be able to start Lightroom.

JimHess Mar 14, 2015 5:33 PM (in response to mcmre1)1. Open Windows Explorer (Windows) or Finder (Mac).
2. Open the folder that contains your Lightroom catalog.
3. In that folder, look for a file with the .lock extension. If your catalog is named Lightroom 5 catalog.lrcat then the file will be named Lightroom 5 catalog.lock.
4. If you find such a file, highlight the file and delete it. You do that by pressing the delete key.
5. Close Windows Explorer or Finder.
6. Start Lightroom as you normally would.
In case you don't know where your catalog is located, if you are using Windows it will be located in Pictures\Lightroom. I'm not sure what the path is for the Mac.

mcmre1 Mar 14, 2015 5:44 PM (in response to JimHess)Jim, I'm not getting to the right catalogue location. I go to the bottom left and right click to get choices, can search or use file explorer. I assume file explorer is the correct one but not getting to where I need to be ?
