Known issues in Lightroom Classic

Check to see if the issue you're encountering is a known issue in the latest release of Lightroom Classic.

See Known issues in Lightroom Classic.

Get the latest camera support

The most commonly asked support question is "How do I get raw file support for the latest cameras?"

See Photoshop or Lightroom doesn't support my camera.

Install the latest Lightroom Classic updates

You can fix many problems by simply making sure that your Adobe software is up-to-date.

See Keep Lightroom Classic up to date.


Adobe provides technical support and security fixes for the current version and the prior version. Bug fixes are only provided for the current version. See Lightroom Classic - Supported versions for complete details.

Install operating system updates

You can fix many problems by simply making sure your operating system is up-to-date.

Adobe recommends that you perform your own testing on a non-production partition to ensure that brand-new operating systems work well with your current hardware and drivers.

Creative Cloud doesn’t show available updates, or applications are in trial mode

Not seeing the available updates? Are your applications showing as trials?

See Available updates not listed.

I can't activate Lightroom Classic, or applications are in trial mode

Not able to activate Lightroom Classic, the Develop module is disabled, or applications are appearing as trials? See:

Install graphics card (GPU) driver updates

To troubleshoot your computer's graphics card GPU (Graphics Processing Unit) and driver, see Troubleshoot graphics processor (GPU) and graphics driver issues | Lightroom Classic.

For more information on Lightroom Classic's utilization of your computer's graphics card GPU (Graphics Processing Unit), see Graphics processor (GPU) FAQ | Lightroom Classic.


You can avoid GPU driver crashes, screen/document redraw, blue or X’d-out images, or color display issues by using the latest video drivers. Updated drivers are available from the card manufacturer’s website (NVIDIA, AMD, or Intel).


Simply running Windows Update doesn’t ensure that you have the most recent video driver. Go directly to your card manufacturer's website to check for driver updates.


Your video drivers are included with your operating system updates. Make sure that you have installed all the latest OS updates by choosing Apple menu > About This Mac > Software Update.

Optimize Lightroom Classic’s performance

To optimize Lightroom Classic on your computer, see Optimize performance.

Calibrate your monitor

Corrupt monitor profiles affect both the performance and the color reproduction of Lightroom Classic.

Calibrate your monitor either by using your operating system’s calibration feature or a hardware colorimeter to create a good color profile for your monitor.

For more information on how to calibrate your monitor, see How (& Why) to Calibrate Your Monitor.

For answers to common questions asked about color in Lightroom Classic, see FAQ | Color in Lightroom.

Troubleshoot Missing Photos

When in the Develop module, Lightroom Classic indicates that the photo could not be found, or is offline, or missing, or your images display a missing icon () in image cells in the Grid view and the Filmstrip.

See Locate missing photos.

Troubleshoot Catalogs

See Lightroom Classic catalog FAQ.

If you open Lightroom Classic and your catalog is empty or doesn't have all the images you're expecting, it's likely you've accidentally created a new catalog or opened the wrong or an old catalog. See 

If you encounter the error 'The Lightroom catalog cannot be opened because another application already has it opened' when you launch Lightroom Classic.

See Error: Lightroom catalog cannot be opened.

Managing third-party Online Storage and Syncing services with Lightroom Classic 

In Lightroom Classic, when syncing with services like Microsoft OneDrive or Apple iCloud Drive, be mindful of unintentionally using up online storage. Exclude the Location for Lightroom Ecosystem's Images in your syncing client's settings or specify a different folder location in Lightroom Classic's sync preferences to avoid uploading to your syncing service's online storage.

Troubleshoot Sync

  1. Check with the plug-in manufacturer to see if they have an update for your plug-in.
  2. Disable problematic plug-ins using Lightroom Classic's Plug-in Manager:
    1. In Lightroom, choose File > Plug-in Manager.
    2. Click Disable for each of the listed plug-ins.
    3. Check if the problem is still occurring.

Lightroom Classic doesn't launch on Windows N edition

Lightroom Classic needs Windows Media Feature Pack to launch.

Here's how to install the Media Feature Pack on Windows 10 N and Windows 11 N:

  • Windows 10 N:  Select the Start button, then select Settings > Apps > Apps & features > Optional features > Add a feature.  Then locate the Media Feature Pack in the list of available optional features.
  • Windows 11 N:  Select the Start button, then select Settings > Apps > Optional features.  Select View features next to Add an optional feature, and then select the Media Feature Pack in the list of available optional features.

You'll not be prompted to restart your computer, but you must restart in order to successfully complete the installation of the Media Feature Pack.

For more details on Windows Media Feature Pack, click here.

Troubleshoot user account permissions

If none of the troubleshooting steps above solve your problem, your problem may be related to user permissions.

Click Repair to Continue

If you get the Lightroom encountered user permission issues dialog box on launch, click Repair to Continue in the error dialog box.

Manually change folder permissions

Manually change the permissions on the following folders and all the items in these folders to Read & Write so that Adobe applications can write to these folders when opened or during use:

  • /Users/[user name]/Library/Preferences/
  • /Users/[user name]/Library/Preferences/Adobe/ 
  • /Users/[user name]/Library/Preferences/Adobe/Lightroom/
  • /Users/[user name]/Library/Caches/Adobe/
  • /Users/[user name]/Library/Caches/Adobe/Lightroom/ 
  • /Users/[user name]/Library/Caches/Adobe Camera Raw 2/ 
  • /Users/[user name]/Library/Application Support/Adobe/
  • /Users/[user name]/Library/Application Support/Adobe/Lightroom/ 
  • /Users/[user name]/Library/Application Support/Adobe/CameraRaw/
  • /Users/[user name]/Library/Application Support/Adobe/OOBE/
  • /Users/[user name]/Library/Application Support/Adobe/Common/
  • /Users/[user name]/Documents/Adobe/
  • /Users/[user name]/Documents/LrClassicLogs/ 
  • /Users/[user name]/Library/Logs/Adobe/

Do the following:

1.   Open the user Library folder. To do so, press Option and choose Go > Library in the Finder.


The user Library folder is hidden by default in macOS X 10.7 and later. To locate and access the user Library folder, refer to Can't see user library files on Mac OS X 10.7 and later.

2.   Change the permission on these folders and all items within these folders to Read & Write. To perform the permission changes, refer to the topics Assign permissions to users and groups and Apply permissions to all items in a folder or a disk in the Apple article Set permissions for items on your Mac.


Make sure that you apply Read & Write permission to all enclosed items within these folders. It requires your administrator name and password.

3.    Launch Lightroom.        

Use a script to restore permissions

If the previous solution does not resolve the folder permission issue, try this easy-to-run, shell-script-based solution explained below. This shell-script automatically restores the ownership and read/write permission, and it removes Access Control List (ACL) from the set of Adobe user folders and its subfolders.

To run the shell script, do the following:

  1. Download using the above link. By default, the file is downloaded to /Users/[user name]/Downloads/
  2. Unzip the downloaded zip file to extract the shell script file.
  3. On your Mac desktop, type Terminal in the Spotlight search box and launch the Terminal app.
  4. From the Finder, drag the unzipped shell-script file (from step 2) onto the Terminal window. You see the following text in the terminal window:
  5. Press Enter to run the shell script.
  6. When prompted, enter your Mac login credentials.
    Note: Ensure that you use the account with administrator privilege to log in.
  7. Launch Lightroom.

Set up a new admin user account

Create an admin user account to identify permissions problems. For instructions on creating an admin user account, see the following: 



Be sure to change the New Account pop-up window from [Standard] to [Administrator] when creating the user.

If you still experience trouble on macOS, try repairing the permissions on the disk. For details, see Repair disk permissions with Disk Utility.


If you encounter a user permission error when you launch Lightroom Classic, see Lightroom encountered user permission issues on launch for solutions.


After you create the admin user account, log in to the new user and run Lightroom Classic to see if the problem goes away.


Using the Repair Permissions command repairs permissions for the operating system, but not for applications, such as Lightroom Classic.

Start in safe mode to troubleshoot system add-ons and utilities

Sometimes, third-party extensions and other utilities can interfere with Lightroom Classic’s operation.

If you start your computer in safe mode, third-party extensions and utilities are turned off, which can help solve your problem.


  • Starting up in safe mode: On macOS, safe mode disables all third-party extensions and startup items. It runs only required kernel extensions and Apple-installed startup items.
