Ligthroom start problem error "catalog cannot open another application already has its opening."

My computer is automatically disabled, while I was with lightroom application, and when I turned back on and I wanted to continue my work, this message appeared on my screen and I can't use it.

What can I do?

Thank you

Hi lizettp,

With Lr closed go to the location where your catalog (by default it is pictures/Lightroom)

Delete the. Lock file with the same name as your catalog. For example, in the image below, it is Lightroom4 catalog.lrat.lock

In your case, it will be Lightroomcatalog.lrcat.lock

Restart Lightroom

Let us know if this helps

    Thanks Geoff. I was finally able to locate the "." lrcat.lock' of the relevant folder to the catalog I want to open. Once I deleted it, LR5 was able to access my images. Problem solved. Thank you

    Cannot open catalog in Lightroom

  • LR4/Lightroom 4 - trouble catalogues opening because "another application already has its opening."

    Hello!

    I recently upgraded from LR3 LR4 to, at the same time spend a Mac on a Windows computer.

    I use LR4 successfully for the past weeks, including yesterday.  But today, as I tried to open LR4, two things happened: 1) the window that contains recently opened catalogs only showed my very newest catalog, not others as is usually done, and 2) when I tried to 'open the catalog different' I got an error message.  The error message said: "the Lightroom catalog named '{catalog name}' cannot open another application already has its opening.»  Leave the other copy of Lightroom before trying to launch.

    I have only one copy of LR, this is why it confuses me.

    I thought that maybe there was a little problem somewhere, so I opened the task Mgr "End task" on Lightroom and try again.  Problem was, he showed that LR did not work (it wasn't because I clicked on 'exit' when I received the error message says, who have released the program).  Thought that was weird, so I restarted the computer, thinking that might help.  That did not work.

    I googled my problem and found a somewhat similar situation, in which the person uninstalled/reinstalled LR and everything was back to normal.  I tried this as well, but it did not work.

    I always get the same exact error, if I try to open the LR catalog, or go to the folder that contains the catalog and clicking on that.

    Any thoughts?  I am very frustrated and I have a lot of images to process this week.  (I miss my Mac)

    Thank you very much!

  • I am trying to open Lightroom and he says: "the Lightroom catalog named"Lightroom Catalog"cannot open another application already has its opening.

    lightroom error.PNG

    I tried to open Lightroom and this message keeps popping up. I restarted and shut down completely my computer and that did not work. I uninstalled Lightroom and re installed several times and that has not worked. And I went in my task manager and closed all applications and that has not worked. I don't know what else to do. Help, please.

    Using Windows Explorer, go to the folder containing the catalog, it is usually inside the images folder.

    Delete the file that ends with the extension .lock. Do not remove anything else, now launch Lightoom.

  • Cannot open another application already has its opening

    Help, please.  I always use this catalogue only.  now, I get this error.  I am under lightroom 5.7 64 bit.  I have no other programs using these files.  Thank you

    Go to the directory where is the catalog and delete the file with the extension ".lock".

  • error. Cannot open the Lightroom Catalog

    Hello, I receive the error message: "the called Lightroom Catalog catalog Lightroom 5 cannot open another application already has its opening" at the opening of Lightroom. There is no other application don't use it. There is one file available, not back to the top I was download a catalog of 5.3 TB over the past 4 days and has not stopped. RAW files are sitting on a separate hard drive to the laptop where the Lightroom Catalog is. I can't access this catalog now. I had a crash before it happens... someone can help here?

    You must go to the folder where your catalog and look for a file with .lock extension. This file must be deleted, and then you can again use your catalog. Sometimes, if Lightroom closes abnormally, the lock file is not removed. And that's what causes this error message.

Just in case I have copy the document into my local PV, I can read without problem. Server is mapped in my FileExplorer (Win7). So boring and big bug I think.

  • My iCloud and shared calendars has stopped working in MS Outlook today.  They worked yesterday.  Now, I get the error message "cannot open this series of records.  The information store cannot be opened?  I tried the fix standard support.

    My iCloud and shared calendars has stopped working in MS Outlook today.  They worked yesterday.  Now, I get the error message "cannot open this series of records.  The information store cannot be opened?  I tried the fix standard support.

    Same thing here.  Looks like Windows did an automatic update during the night, and now nothing iCloud associated work (calendars, contacts, etc.)

    I also noticed that the error message: "could not load file or Assembly ' MOM." Implementation ' or one of its dependencies.  The system cannot find the specified file. "It started after restarting the Windows Update as well.  I imagine that the two are related in the same problem to iCloud.

  • error LNK1181: cannot open input file "... \..." \.. \build\win\objR\PMRuntime.lib'

    I have create a new Plugin.

    But happen error LNK1181: cannot open input file "... \..." \.. \build\win\objR\PMRuntime.lib'

    Why?

    I looked at the project and have it fixed with success, but unfortunately I can't send that overall because of the way the project was sent initially. Most absolute paths are the paths used in the project file and that's your project needs changes to much space when focused on a new machine. I'll give you advice on how to solve your problem and how to improve the project is configured for better portability.

    How to solve your problem.

    1. Remove $(MODEL_PLUGIN_LINKLIST) from the list and it will work well for you. The wrong way is written in the sdk file attachments that are included in your file accessories
    2. After taking the first point, you will again have a binding error, to solve, it adds ASLSupport.lib to the additional dependencies in the section of the linker.

    How to set up a project in a more portable way

    1. You should avoid using absolute in several locations paths, because when you move the project to another machine, you will need to change the paths to all these places
    2. Even using relative paths does not solve the issue properly, because in this case you must place the project from a location on each computer so that it works correctly. This is the reason why it was not $(MODEL_PLUGIN_LINKLIST) for you. The Adobe sdk samples use relative paths, so move the project so that by using their configuration fails if the relativeness of the road is not maintained
    3. In order to be totally portable, we should make use of macros and define them in one place. So that when you move the project, change the paths in this single file solves everything. An example of this is how you set the id_sdk_dir macro in your file attachments.

    Hope these points help you to solve your problem and put in place the project in a better way.
