Based on posted recommendations here, I updated my LR C to 12.1., however, I still do get the error message and am not able to open LR at all.
What shall I do?
Adding bug number
It seems Lightroom wasn't closed properly and so there's remaining a .lock file besides the catalog file.
If Lightroom is running it creates a .lock file for the opened catalog next to the approriate .lrcat file.
On LRs regulary shut down this file was deleted. If LR crashes the .lock file remains in the appropriate folder.
In this case the .lock file must be deleted manually.
More informations about this, you'll find here:
The Lightroom catalog cannot be opened because another application already has it opened - lrcat.loc...
Another point could be that Lifghtroom doesn't have full access rights to the folder with the catalog file. Please check if LR does have full right to the appropriate folder.
Hi, I am trying to open a catalog in Lightroom 12.1 on windows 11 22h2. The catalog has been moved and than moved back to original position. Now a get an error : lightroom kan pixelmaskeropslag niet initialiseren.
Thank you for the reply. I tried to follow these steps, however, I cannot find any .lrcat.lock file in my Catalog...
Do you has rebooted your computer?
Please do a cold boot!!
I can not open Lightroom CC due to error Error Message: Failed to initialize pixel-mask storage (Windows 11)
I have read a lot of posts. I have deleted lock files, I have restarted PC numerous times. I have shut down and started PC numerous times. I did a search for lock files and found none.
I have tired the above and still can not open.
No Lock files
Yes, I've rebooted and it did not help.
Any other idea how to fix it?
No, this has nothing to do with improper closing of Lightroom and a .lock file that needs to be deleted. Quite the opposite. The error says that Lightroom needs to create a lock file, but can't. This was a known issue with Lightroom Classic 12.0.1 and was supposed to be fixed in Lightroom Classic 12.1. Apparently it was not fixed completely. The discussion about the problem in 12.0.1 mentioned the following work-around, which is worth trying now as well:
Thank You.....this worked. I found the Current folder in the Lightroom Catalog-2-2-v12.lrcat-data.
Thank you agian for your help.
Thank you very much for reply!
I tried to follow it, however it doesn't work either.
Here is the catalog, however there is no file called Current:
Do I follow it correctly?
First find the Lightroom Catalog-2-2v12.lrcat-data
Then double click it.
Then rename CURRENT
Then open Lightroom, you will get error message again, then opne Lightroom again and lightroom should open. This is what I did and it worked. I hope it works for you.
Great!!! It works!!!
Thank you so much!
This morning when trying to launch Lightroom Classic I get the following error message:
Failed to initalize pixel-mask storageFailed to create lock file inside the folder: Lightroom Catalog.Ircat-data.
The process cannot access the folder because it is being used by another process.
As mentioned, this just started happening today. Lightroom Classic is up to date. My OS is Windows 11 which is also up to date.
Any suggestions on what is causing this and how to fix?
Check that the folder conating the LrC catalog doesn't already have a lock file. If it does, then delete same and retry launching the application.
There is no lock file
The problem is not a .lock file in the catalog folder that needs to be removed. The problem is that Lightroom Classic needs to create a lock file inside the catalog.lrcat-data folder but can't. I gave the solution earlier in this thread, so just scroll back to the previous answers.
also to get to that view you may have to right click and select show package contents if on a mac
Received the following error. I installed LRC 12.1 and restarted the computer but still experiencing this issue.
It's a known issue. The thread discussing same can be seen at https://community.adobe.com/t5/lightroom-classic-bugs/p-updated-to-12-1-amp-seeing-quot-failed-to-in...
Failed to initialize pixel-mask storage
'Failed to create lock file inside the folder: Images Catalogue-2020-v12.lrcat-data.
The process cannot access the folder because it is being used by another process.'
This started happening today and I can't work out how to fix it, can someone please help! Thank you
In System Preferences ((System Settings in Ventura), >Security & Privacy, >Full Disk Access, do you see Lightroom listed? If not, do add it and try again.
Yes I have given added it/ given it full access but it is still coming up with the error
A fix is in this thread.
This is a Windows solution, is there a Mac solution?
