Lightroom can't batch process AI denoise selection. It stops while about 1/10 of the way finished and never finishes. Once you cancel, it never lets you apply that denoise to them again. "Requested adjustment is not applicable."."

Correct answer Justin L. Stewart

UPDATE: It’s working again! I’ve done everything in this thread except for the delete and re-import steps. The oldest suggestions did nothing. Yesterday uninstalled and reinstalled older versions several times. I deleted both the /Library/Application Support/Adobe/CameraRaw/ModelZoo/ files from the system and the user libraries.

I messed with the Camera Raw settings in the preferences. Changed those between auto and off and on and back to auto. I deleted the GPU config files from Solution 3 here: https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html

None of it seemed to resolve my problems, but my harddrive just disconnected while I was running Lightroom and so it was doing a rebuild of my library and I randomly tried clicking the denoise button again on a prayer and it actually worked. I maybe should have restarted my whole computer yesterday after doing everything and tried then, as this was not working when I went to bed.

This all came about from trying to batch use the Denoise AI option. I will not do that again as it’s obviously a broken function.

So, maybe I’d do all the steps I did including uninstalling completely and doing a fresh install and then run an optimize catalog function or something that helps rebuild and clean the catalog.

Hi @Justin L. Stewart, thanks for sharing your troubleshooting process and I am glad to hear it is working again. Please let us know the results if you try another refresh. Thank you for being a part of the community! ^CH

Hi @Justin L. Stewart,

Thanks for reaching out and reporting the issue. Have you tried the workaround shared by Dr. Tony B, and did it help? If not, since restarting Lightroom does not help and the issue is now affecting newly imported photos as well, Denoise eventually becomes unavailable with the message “Requested adjustment is not applicable.” I’d like you to try clearing the local AI model cache first:

• Close Lightroom Classic completely
• Go to system Library: /Library/Application Support/Adobe/CameraRaw/ModelZoo/

and also from User Library: ~/Library/Application Support/Adobe/CameraRaw/ModelZoo/

• Delete everything inside the ModelZoo folders
• Relaunch Lightroom Classic and test Denoise again

If the issue continues afterward:
• Please test in a brand-new catalog with only a few sample files
• Share a short screen recording showing batch Denoise starting, where it stalls, and the “Requested adjustment is not applicable” error afterward.
• Share a few affected sample RAW files
• Copy & paste your full System Info from: Lightroom Classic > Help > System Info

We are looking forward to hearing back from you.

Best,
Anshul Saini

Did you steps. Deleted everything in both ModelZoo folders. Didn’t do anything different.

Made a new catalog and imported a couple photographs. Didn’t work. Attached is a screen recording. Photographs are all made with Sony A7III.

@Justin L. Stewart

I downloaded your two files and they Denoised without any problems on my Windows 11 PC.

Your System Info has

Graphics Processor Info:

Init State: GPU Unsupported

Is this the case?

You might try deleting the GPU config files; see here

https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html

In particular, follow the instructions under this section

Solution 3: Force Lightroom Classic to use Windows DirectX or macOS Metal

I selected 45 photos, all 46mp from my Nikon Z8,and batch applied Denoise. Completed without any problems. I do not use xmp sidecar files, so have auto save to xmp turned off.

I’ve used it prior without issue. I’m wondering if there was a recent update that triggered this issue.

What were the results for step 2?

Justin L. StewartAuthor

I imported new photos and the denoise has the same error pop up for any photo I try to apply it to now.

I’ve restarted multiple times. It does nothing. I can’t find any xmp files in the photo folder.

To narrow down where the problem is and file an actionable bug report if necessary:

1. If you restart LR, does the problem go away, at least for a little bit?

2. Try removing one of the photos from the catalog for which you got that error. Look in the folder containing the photo and delete any accompanying .xmp sidecar. Then reimport the photo and try to apply Denoise -- do you still get the error?
