I can't open Lightroom 3.2 on my PC.

I can't open Lightroom 3.2, on my PC. The pop up says: Lightroom 3.2 cannot be opened because it is already open in another application. '

Never had this experience over the past four years. I can't find which application it is, so I can't close it.

Urning edited PC stopping and restarting does not help. Does anyone know how to fix this? Thnx!

Use Windows Explorer to open the folder that contains your catalog. In Windows, the default location is Pictures\Lightroom. In this folder, you will find a file with .lock extension. The file name must be the same as your catalog. After deleting this file Lightroom should restart normally for you. Do not delete any other files or folders. This lock file is one that is created by the catalog each time that Lightroom is open. If Lightroom stops abnormally or if there is some kind of problem then this file can be left.
