Lightroom catalog cannot be opened ...

In Lightroom 5: After having put off the computer without having closed Lightroom before and restarted the computer,  trying to start Lightroom results in 0 pictures shown and a fault message saying "The Lightroom catalog named Lightroom 5 Catalog cannot be opened since it is already opened in another program". (My translation from Swedish.) I can´t find any program that could be responsible for that in the activity handler in the computer.

In addition to what Just Shoot Me​ has said, it may be that you are looking at the wrong folder and the wrong catalog. Please use your operating system's search feature to find all files whose name ends with .LRCAT on all hard disks, and then see if any one of them has a .lock file in that folder (and delete the .lock file).

Using your operating system, you need to find a file whose name ends with .lock in the same folder as your catalog file. Delete this .lock file. Do not delete anything else.

So you found a file with the extension of .LOCK and you deleted it? Correct?

What happened after you deleted it and tried to open LR. Please be specific.

So LR doesn't open and you get no error message?

Locate the catalog file, it ends with .lrcat, and double click on it. What happens?

What exact OS are you using?

If you had already done that, you could have mentioned it in the first place.

However, you may have deleted the wrong .lock file. Show us a screen capture of the folder in your operating system where your catalog file is stored.

What happens when you double click on that .lrcat file you show in the File Explorer window.

Do you have any current backups of the catalog file? By default LR is set to make a backup of the catalog file once a week.

Use the search feature of File Explorer, upper right hand corner, to search your drives for .lrcat. What comes up.

I am have the assumption that your install of LR has been corrupted. you can try reinstalling it from this link.

Also your catalog file looks very small, 1352 KBs.

My LR 5 cat file is 298,444 KBs. My LR 6/2015 cat file is 335,920 KBs. My LR C CC cat is 233,000 and adobe has made changes to the LR C CC catalog to make is smaller.

I have a test catalog for LR C CC that has only 7 images imported into it and that is 31,896 KBs in size.

So the cat file you are showing in that screen shot looks like it was just created with no images imported and or very few images and no adjustments.

I just opened LR 5 on my system and created a new catalog. That new catalog with no images in it is 1,352 KBs in size. The exact same size as the cat file you are showing in your screen shot. So either you just started using LR 5 and created a new catalog or you are not open the correct catalog. There must be another catalog file on your system.
