Cannot open the Lightroom Catalog because he is "busy in another program" - what can I do?

I tried to restart my computer (three times...) and reinstall the program - no use.

I have no idea what program uses the catalog or anything that doesn't go there.

Help, please!

Try looking in your catalog file to see if there is a file with .lock extension. It should have the same name as your catalog file if we're here. If you find such a file, you must remove it. Once you do that Lightroom should start normally.

  • Cannot open the Lightroom Catalog because another application already is open.

    I hard a message that another application has the open catalog, but I have no idea what's open. Any ideas on how to understand what program it was open?

    When Lightroom has an open catalog it creates a temporary file next to the catalog file, which has the same name with an extension .lock. By default, the files are located as shown in the attached screenshot.

    If Lightroom is not normally closed the .lock file will remain in place and prevent Lightroom opening of the catalog said.

    With Lightroom closed go to the subfolder of Lightroom, and if there is a file with the name of .lock extension remove the file, and then try and open Lightroom.

  • 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.

    Go in the same folder as your Lightroom catalog file.

    In this folder is a file whose name ends in. LOCK (probably all lowercase). Delete this one. LOCK file. Do not remove anything else.

  • Cannot open the Lightroom catalog on external drive

    Please excuse the screen name. I tried so much to during registration, but they were all taken while I was sure that it would be available.

    I'm moving from a PC to a Mac laptop.

    I copied my drive whole photo on an external drive, which is what I use with my laptop. My catalogue and photos are stored on this external hard drive and when I try to open the catalog, I get the following error:

    Lightroom does not start with this catalogue. It is on a network volume or a volume on which Lightroom is unable to save the changes. But I have no problem opening an image in Photoshop so I know not the files being copied in a readable format.

    Ideas?

    Hi somedaymetalkpretty

    I suspect that your external drive is formatted with the NTFS file system, which is normal for Windows, but impossible to write in Mac. You will need to use an external hard drive formatted to FAT32 if you want to use in Windows and Mac.

    Beat

    PS: I guess that your catalog (.lrcat file) does not exceed 4GB, otherwise you would have a problem with FAT32.

    My Lightroom does not. It is showing the message - failed to open the Lightroom catalog called Catalog Lightroom because it is too new to be used by this version of Lightroom. You want to select a different catalog?

    It is a catalog that you created on your computer, or coming from another computer?

    If it is one that has been created on your computer, you can search your computer to see if you have two different versions of Lightroom installed. If so, then you want to open the new version of Lightroom by double-clicking its icon, and then you should be able to open the catalog.

  • Cannot open the application "Mail" because PowerPC applications are no longer supported

    I work on a MacBook Pro mid 2012

    Intel Core i5 2.5 GHz

    OS X El Capitan 10.11.6

    The Mail app suddenly quit and when I tried to resume, I got this message

    "Cannot open the application"Mail"because the PowerPC applications are no longer supported."

    This also happens with the "Maps" app

    All Mac software are up to date, but "Mail" has been working fine since my last update that was awhile ago.

    I am confused to say the least. Suggestions? Thank you!

    If you do a Get Info (command - I) on Mail and Maps applications, what version numbers do you see?

    Try a reboot.

    Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

    Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in system preferences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

    Isolate a problem by using a different user account

    If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

  • Lightroom - how to restore backed up files (not the Lightroom Catalog) from one external drive to another?

    How to restore backed up files (not the lightroom catalog) from one external drive to another.

    I've recently saved my photo files to one external drive to another. The backup (carbon copy clone) pointed out some files corrupt on the original drive.

    I deleted these files and find good copies of Time Machine backups.

    I want to get rid of the original external drive; use the recent backup as my main outside and then save it to a new disc.

    I'm not sure how everything is point lightroom for backups so he knows look on the new drive instead of the old drive and all points of exclamation and question marks go away.

    There are close to 60 000 images in several files with a 'parent folder."

    My best guess is Lightroom Help - create and manage folders - locate missing files

    Can I point to the folder of one of their parents, and all of the subfolders will return?

    This is the process for recovering files in lightroom and there will be a problem with so many photos?

  • Cannot open the application "iTunes" because another user is open.

    I recently bought a new computer with vista. Installed iTunes on this computer and found that there is a problem between the two profiles on the computer. I run iTunes on my profile - but whenever my wife profile is active we are getting consistent error messages indicating "cannot open the application"iTunes"as another user, he has opened." Ask the other user to quit the application and try again.

    I need to keep itunes open in my profile - and anyway, why are they bent them in two profiles in Vista... we never had this problem under XP.
    I asked Apple for advice, and they suggested to install itunes in the second profile... which I did and said to reinstall/repair...which is not the goal... Apple then told me to contact Microsoft support as he would have to do with the admin files...
    Any advice pls.
    Thank you

    Find the Itunes.exe in the Itunes folder in Program Files.  Right click on the .exe / Properties / compatibility, look down at the bottom of this page for the 'privilege level' and check the box that says "change settings for all users.  In the heartbeat window according to the box that says "run this program as an administrator".  This can only solve your problem if you can both run under the same user name.

    When you run a program as an administrator you should get a quick UAC (unless maybe you have turned off UAC?

    To see the file extensions, you may need to go into Control Panel / folder Options / discovers, there you can uncheck "hide known file type.

  • Cannot open the Lightroom

    I got lightroom for a year, but for a few months now lightroom just will not open. I click on the app and it comes up with a box saying "Lightroom catalog named"Lightroom Catalog"cannot open another application has opened" and gives me the option to choose a different catalog, to continue or exit, but if I try to choose another catalogue none of my catalogs are here. Does anyone have an Adviser on how to solve this problem? I already tried to uninstall lightroom and enter the taskmanager to shut what is open and they do not work.

    Charlotteb salvation,

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

    Remove the . Lock file with the same name as your catalog. For example, in the image below, it is Lightroomcatalog.lrcat.lock

    • Rename or delete the Lightroomcatalog.lrcat.lock file.

    • Restart Lightroom

    Let us know if that helps.

    Kind regards

  • Still trying to open the Lightroom Catalog and stops

    I tried to import a picture from a file on my computer. The Lightroom 3.6 Lightroomstopworking.JPG program stops.  When I try to open the program, a message appears that says "Lightroom - opening catalog: DSC_2155.lrcat.

    Immediately after that that appears on my screen, that a box appears that says "Adobe Photoshop has stopped working" below to bed "a problem caused blocking the program works correctly.  Windows will close the program and notify you if a solution is available. »

    Of course I never am notified and a solution is never available.  I tried to delete Lightroom and reloading the program, but the same problem occurs.

    is there a way to fix this?
