Today, my Lightroom Classic CC won't open. It was fine yesterday. Today it will only show the opening splash screen and then nothing, it just goes away.
I'm running on a new iMac with the latest updates on it. As the programme ran yesterday, I'm pretty sure it's not the machine that's the problem.
I can see this is a really common issue and the advice is to sign out of your account and sign back in. I have done that, several times. The support page also tells you to clear out some subfolders that just don't exist on the Mac but that whole folder went when I uninstalled.
I have uninstalled it and reinstalled, twice. I have uninstalled every Adobe app and run the AdobeCreativeClouldCleaner tool to remove them all. I've shutdown an restarted multiple times.
When I reinstall, Lightroom still won't work.
I'm at a loss as to what to do next.
Anyone able to help?
Open the folder that contains your Lightroom catalog (probably in Pictures). Look for a file with 'lrcat.lock' extension. Remove it to trash, then try restarting Lightroom.
I tried that but it still won't open and recreates a new .lrcat.lock file.
You got me thinking though so I moved the catalogue out of the pictures folder and now Lightroom starts.
It must be something to do with the catalogue.
You've given me another avenue so thank you!
I've gone back to my previous back up and all is working again.
It's interesting but thank you for helping!
The holy grail of answers....
Checked forums first and didn't find an answer that helped (didn't find this one). Spent two hours on chat and remote with Adobe Support...found nothing except a glass of wine in my hand. Found this. Removed the lock file...didn't work. Moved my catalogue to a different file path and ….voila!
It's 2021 and the same issue for me. Workef my way through this thread, tried the suggestions.. Restored 5 versions of my catalog backup, reinstalled lightroom photos from backup and no joy. Then I tried your solution, and it works as promised. When will I learn to start with the LAST reply and work backwards?
Thank you for your persistence in solving this, and for posting your success!
Any chance yo ucan share exactly what yo udid? I am having same issue with no luck. I don't know how to "move my catalogue to a different file path"... HELP!! TIA!
