I can't open Lightroom 3.2, on my PC. The pop up says: Lightroom 3.2 can not be opened because it already opened in another application. '
Never experienced this in the past four years. I can't find which application it is, so I can't close it.
urning PC off and restarting doesn't help. Does anyone know how to solve this? Thnx!
Use Windows Explorer to open the folder that contains your catalog. In Windows The default location is Pictures\Lightroom. In that folder you will find a file with the .lock extension. The filename should be the same as your catalog. After you delete that file Lightroom should start again normally for you. Do not delete any other files or folders. This lock file is one that is created by the catalog whenever Lightroom is opened. If Lightroom shuts down abnormally, or there is some kind of a problem then this file can be left behind.
Problem solves, thank you!
