Copy link to clipboard
Since the latest update to version 11.1 I am unable to launch LrC due to this error and I don't know what it mean when there are no other programs using Lightroom catalog.
"The Lightroom Catalog named "Lightroom Catalog" cannot be opened because another application already has it opened." Quit the other copy of Lightroom before trying to launch.
Can anyone help?
I am using Windows.
Have you looked to see if the lock file was not deleated:
Thank you! This worked by deleting the file name you mentioned.
