If you’re having a problem with Lightroom, there are some general troubleshooting steps you can try. (As always, make sure you have backups before you try any troubleshooting steps.) We’ve run through the steps for both Lightroom (cloud-based), and also Lightroom Classic. Not all steps apply to both variants. (Lightroom Classic instructions also apply to most older Lightroom versions also).
1. The magic reboot
If you’re having odd problems with any computer program, the age-old wisdom “turn it off and turn it on again” still works wonders. First, try restarting the program, and if that doesn’t solve it, reboot the computer.
2. Optimize the Catalog (Classic)
Go to
and wait for it to tell you it’s completed before moving on.3. Check For Lightroom Updates
Next, check for updates, as the issue you’re running into could be a bug that’s been fixed in a later release. Make sure you’re running the latest updates, both for Lightroom (by going to
) and also for your operating system.4. Check for Driver Updates
Buggy graphics card drivers can cause no end of trouble.
On Windows, check the graphics card manufacturer’s website for an updated driver as Windows Update often has outdated drivers. It’s best to uninstall the previous driver before installing the new one.
On macOS, check System Preferences > Software Update for an operating system
update.
5. Turn off the GPU
If you continue to have problems, particularly with artifacts on the screen, slow performance or crashes, try turning off the GPU. For Lightroom 6, go to Preferences > Performance tab and uncheck Enable Graphics Processor. In Lightroom Classic or Cloud, go to Preferences > Performance tab and set Use Graphics Processor to Off. If this solves the problem, it’s definitely a graphics card conflict.
6. Reset Preferences
If you’re still having problems, resetting Lightroom’s Preferences file can solve all sorts of ‘weirdness,’ so it’s a good early step in troubleshooting.
There’s a simple automated way of doing it—just hold down Alt and Shift (Windows) / Opt and Shift (Mac) while opening Lightroom and it’ll ask whether to reset the preferences. The timing is crucial—hold them down while clicking/double-clicking on the app/shortcut.
Alternatively, you can reset the preferences manually. Moving or renaming the preferences file, rather than deleting it, means that you can put it back if it doesn’t solve the problem, to save you manually recreating your preferences again.

7. Cleanly Uninstall and Reinstall Lightroom
Particularly if the problems started just after an update, an uninstall and reinstall can help. If the computer hadn’t been rebooted for a while before installation, the installation can be incomplete, so:
- Reboot the computer.
- Uninstall Lightroom Classic / Cloud using the Adobe CC app.
- Reboot the computer.
- Reinstall Lightroom Classic / Cloud using the Adobe CC app (or Lightroom 1-6 using your original disk).
- Reboot the computer.
- Pat yourself on the back, go make a drink, come back and see if the problem is solved.
8. Try a new catalog (Classic)
If resetting the preferences doesn’t help, create a new catalog to rule out minor catalog corruption. (Note that this is only a test to check whether the problem is catalog-specific. Don’t delete your working catalog or start working in this temporary catalog!) To do so:
- Go to .
- If you can’t open Lightroom to access the menu, hold down Ctrl (Windows) / Opt (Mac) while restarting Lightroom, then click the Create New Catalog button.
- Choose a location for the temporary catalog such as the desktop.
- Import some photos into this new catalog to check everything is working as expected.
- If this works, the problem is likely specific to your catalog. Don’t panic, that can usually be fixed, but you’ll need some help so post on the forum.
- To return to your normal catalog, go to File menu > Open Recent.
9. Rule out corrupted presets (Classic)
The next thing to check for is corrupted presets, as they can cause strange problems like module hanging and performance problems. To do so:
- Go to Edit menu (Windows) / Lightroom menu (Mac) > Preferences > Presets tab.
- Press the Show Lightroom Develop Presets and Show All Other Lightroom Presets buttons. This will open two Explorer (Windows) / Finder (Mac) windows to the Lightroom and CameraRaw presets folders.
- Quit Lightroom.
- Select the contents of the Lightroom folder, with the exception of the Preferences folder (as we’ve already ruled out preferences problems). Move these subfolders (e.g. Develop Presets, Print Templates, etc.) to another location, such as the desktop.
- Select the contents of the CameraRaw folder and move it to another location such as the desktop.
- On macOS, you’ll need to reboot the computer as macOS caches some files.
- Restart Lightroom.
If it does solve the problem, copy the presets back a few at a time, to narrow down which specific preset (or group of presets) is causing the problem.
If the problem isn’t solved, you can copy the preset folders back, overwriting the default preset folders that have been automatically created, and we’ll try something else.
10. Rule out corrupted fonts (Classic)
Corrupted fonts have also been known to cause problems, particularly in the Print and Book modules. Fonts aren’t specific to Lightroom. If you’re not familiar with managing your operating system’s fonts, Google “uninstall font” and the name of your operating system for instructions on removing fonts.
11. Try a clean user account (Classic)
Sometimes issues are specific to your computer’s user account. Testing a clean user account can rule out a lot of potential problems in one go. If you’re not sure how to create a clean user account, click here for Microsoft and Apple’s official instructions.
12. Check for hardware and operating system problems
Lightroom taxes your computers hardware more than most of the programs you use, so it often finds hardware and operating system problems that don’t show up in other software.
Damaged RAM can also cause some odd problems—Lightroom finds dodgy memory quicker than almost any other program. You can easily check that by running software such as Memtest.
Depending on the issues you’re having, check other hardware for issues, for example, if Lightroom’s running slowly, check the hard drives, particularly if it’s an intermittent problem. They could be dying or just running low on space.
If the screen is behaving oddly, check your graphics card, monitor and calibration. If you’re having problems importing, check your card reader, USB ports and the destination hard drive.
Also check your boot drive to ensure it has plenty of space available, as a lack of space for operating system temp files can cause all sorts of problems.
13. Ask for help!
If none of these troubleshooting steps solve the problem, post a description on the forum and we’ll try to help you figure it out!
For extensive information on Lightroom Classic, see Adobe Lightroom Classic – The Missing FAQ.
If you have the Photography Plan, then as well as Classic you have access to the Lightroom cloud ecosystem including the mobile apps and web interface. For more information on these apps, see Adobe Lightroom – Edit on the Go.
Note: purchase of these books includes the first year’s Classic or cloud-based Premium Membership (depending on the book purchased), giving access to download the latest eBook (each time Adobe updates the software), email assistance for the applicable Lightroom version if you hit a problem, and other bonuses.
We also have a special bundle offer for the two books. This includes Premium Membership for the first year as described above for the whole Lightroom family!

Hi – I am using LR5.7 and when i open programme it shows – error Lightroom encountered an error when reading from its preview cache and needs to quit
I have as suggested deleted preview file, but the problem is still there, thus cant use LR5, sooo please any ideas etc, but in layman terms as i am not good on computers
Paul McFarlane says
Try Purge Cache (in Preferences) – it could be a corruption in there.

I am having problems with the LRC for some time now. It looks like “it doesn’t listen ” to the mouse commands. I am using Windows.
I checked the mouse batteries, they are new.It’s been recently updated . But still the same problem. LRC doesn’t respond to many crucial commands like: cropping, moving a bit any sliders, radial filter instead of it’s purpose reacts like a zooming tool.Any changes I wanted to edit appears much later, not right away. It makes my editing work really difficult.
Any help?
Thank you very much.
Victoria Bampton says
Is it just a basic mouse, or does it have a separate driver? It sounds a lot like a driver issue rather than a Lightroom one. Or some kind of accessibility feature turned on in the operating system that’s changing normal behavior.
Malcolm Wells says
Since the last upgrade of Lightroom CC on my Mac the email client no longer links to Apple Mail. Have been through all the suggested fixes I can find in forums but without success. Any suggestions?
Victoria Bampton says
I can reproduce that, I’ll bug it

Lightroom 6 crashed repeatedly moments after I opened it. You rescued me with #4. Thank you!
Paul McFarlane says
Excellent, we’re very pleased! It’s amazing how often GPU causes issues.

Hi Victoria,
I’m having a big problem opening LR 6.5 on my Macbook Pro ( running 10.9.5 ) since yesterday when I tried for the first time to process a file in NiK Collection via LR.
I chose Edit in > NiK Sharpener and then Define. The plug-ins opened but could not load the image properly – I got a black and white squares covering the whole image preview pane. I knew the image was there as I could see the file name and the sliders were working. I went to NiK help and found this:
https://support.google.com/nikcollection/answer/3002572?hl=en&ref_topic=3002209
I followed the instructions to delete duplicate Arial fonts ( I did have them – greyed out and off ) and rebooted my laptop. Opened Nik Sharpener from LR again but there was no difference – still black and white squares.
I then ( stupidly ) decided to save the file back to LR. I appeared in LR as a solid black background. I closed LR and from that point onward I was unable to launch it again. I crashes on start up every time with Adobe crash log generated but I cannot understand it. At one point I was able to see that LR is “stuck” on that particular file while opening – i.e the black image is highlighted in preview while LR is trying to open. It crashes before I am able to choose another image for opening.
I uninstalled NiK collection and all associated files in HD/Library/Preferences/ Google. I did not help.
I then logged out of my admin account and tried Guest – it worked. I can open LR from Guest account but obviously it has no catalog or any images and as Guest I can’t save anything.
So it looks like that particular file from NiK is somehow corrupted in LR catalog on my admin account and crashes LR on launch but I do not know how to delete it or otherwise solve the problem. I do have a LR backup from 6th May but again I do not even know how to use it.
Please help !!

Ooooops, sorry Matt. Not usually – I’m just in the middle of upgrading the forum software so it’s protected for a few hours.

Does this link actually require a userid & password?
Victoria Bampton says
It’s live again now!
Edward says
After all that was said, re-install the program sometimes that corrects the problem providing it’s after a recent install.
Victoria Bampton says
Excellent point Edward!
Carolyn Valentine says
I can see I have imported 37 images as they are on the previous import part but they have not gone into a sub folder. Trying to import them again they are all greyed out. Is there a way around this so that I can get them into a sub folder? I have tried clicking and dragging but it wasn’t working.
I’m not overtly IT savvy.
Victoria Bampton says
In Previous Import, right-click on one of the photos and choose Go to Folder in Library. That’ll show you where they’re currently stored. You should be able to drag them (by the thumbnail, not the border) to the folder of your choice.
