If you encounter a crash, be sure to submit all crash reports. If you submit a crash report for a known issue and include your email address, we can email you a solution to correct the problem.
The most commonly asked support question is "How do I get raw file support for the latest cameras?"
For more details and answers to common questions regarding camera support in Lightroom, Camera Raw, and Photoshop, see Photoshop or Lightroom doesn't support my camera.
Many problems are fixed simply by ensuring that your Adobe software is up to date. See Keeping Lightroom up to date for details.
For more troubleshooting steps and information on Lightroom utilization of the graphics card’s GPU (Graphics Processing Unit), see GPU troubleshooting and FAQ.
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, ATI/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.
To determine what video card you have and to download/install the most current driver, see Update the graphics driver.
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.

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

You can solve many abnormal and intermittent behavior issues by resetting the Lightroom preferences to their factory-fresh state.
To reset Lightroom preferences:
- Quit Lightroom.
- Start Lightroom while holding the Shift + Option (Mac OS) or Shift + Alt keys (Windows).
A dialog box asks if you want to Reset Preferences or Start Normally.
- Click Reset Preferences.
For more details, see Recover catalog and images after resetting preferences.
If you encounter the error 'The Lightroom catalog cannot be opened because another application already has it opened' when you launch Lightroom, see Error: Lightroom catalog cannot be opened for a solution.
If you have installed many third-party plug-ins and are experiencing odd behavior in Lightroom, troubleshoot the plug-ins next.
- Check with the plug-in manufacturer to see if they have an update for your plug-in.
- Disable problematic plug-ins using Lightroom’s Plug-in Manager:
- In Lightroom, choose File > Plug-in Manager.
- Click Disable for each of the listed plug-ins.
- Check if the problem is still occurring.
- If the problem is resolved, turn the plug-ins back on one by one.
- Check to see if the problem reoccurs after re-enabling each plug-in.
If none of the troubleshooting steps above solve your problem, your problem may be related to user permissions. Using the Repair Permissions command repairs permissions for the operating system, but not for applications, such as Lightroom.
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 Mac OS, 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, 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 to see if the problem goes away.
Sometimes, third-party extensions and other utilities can interfere with Lightroom’s operation.
If you start your computer in safe mode, third-party extensions and utilities are turned off, which can help solve your problem.
- Try safe mode if your Mac doesn‘t finish starting up: On Mac OS, safe mode disables all third-party extensions and startup items. It runs only required kernel extensions and Apple-installed startup items.
- Start your computer in safe mode: On Windows, safe mode starts Windows with a limited set of files and drivers.
Try all the steps above before reporting a problem, posting on the forums, or contacting support for Lightroom issues.
