Lightroom Classic won't launch

I can't get Lightroom Classic to launch. When I try to I get spinning wheel while the computer thinks about it for a second then nothing happens, but Lightroom Classic shows up as a Background Process in Task Manager. This only happens with Lightroom Classic, I also have Photoshop and Lightroom (not classic) and both of those work with no issue. I have tried un-installing + reinstalling including using Adobe Creative Cloud Cleaner but always with the same result (everything except Lightroom Classic works). Is anyone able to help or experienced something similar? Details below.

 

Creative Cloud 5.3.1.470

Lightroom Classic 10.0

Windows 10 Pro Version 20H2

You may have a corrupt Preferences file, which does not get deleted during an uninstall. Close the Lightroom Classic instance in task manager and then hold down the ALT and SHIFT keys and click on the LrC shortcut. When prompted, click Yes to reset Preferences.

 

EDIT: I forgot to add that the Reset Preferences prompt is a small dialogue box, which may be hidden behind other windows. If you don't see it, try minimizing or closing all other open windows.

Glad to hear that worked. To get LrC back to the previous state you'll need to re-enter any changes you had made to LrC Preferences and reinstall any plugins you were using.

Can you please post your own posting on this issue?

 

Why you ask? Because:

 

  • Original posting a good year old, things change, solutions change
  • Your OS is MACOS, original is Windows, different OS can have different resolutions
  • Different version of LrC, Original posting was v10.0, sice then v10.1, 10.2, and now a major change v11. Various bugs fixed along the way, and maybe new bugs introduced

 

When you do post your own posting, please, please, it will be very helpful if you include more system info, following is my SOP on how to do that

______________________

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

I've been having this problem for 5 months. I've checked periodically and still unable to run LRC on my Mac. I've reset preferences, updated OS, updated LRC, granted full disk access, granted read/write access to folders/cache/etc and every suggestion I found from Adobe. I'm not sure if I'm the only one for whom none of these have worked.

I realize this thread is a bit old but the ALT SHIFT thing does not work here. Any other ideas?

Solved this by uninstalling, and the manually deleting the folder under \pictures\lightroom and then doing a reinstall.

Program now launches from Creative Cloud as well App shortcut.

I am using Windows 11 and cannot get LRC to open.  I have unistalled and reinstalled both LRC and LR several times.  Now LRC appears to get hung opening the Catalog.  I have tried to reset preferences, but do not get the dialog when I use the ALT Shift Click on shortcut.  Any help is appreciated.

I have the exact same problem.  I uninstalled LRC, re-installed it, deleted the Lock file and launched it.  LRC came up but when I selected my catalog, it asked if it was OK to close the current (empty) catalog and re-launch with the specifeid catalog.  I clicked OK, LRC closed, re-launched, and got stuck trying to open my catalog with this message on the desktop:

Screenshot.pngMultiple attempts to kill it with Task manager, delete the lock file, and re-launch have failed.  How does one fix this???

I was able to fix this by deleting my catalog and unzipping the most recent backup into the default Lightroom folder.
