P: Win Arm (Snapdragon) reports NEF as an invalid file in Add Photos

I'm having trouble opening NEF files from a Nikon Z8 on a Windows ARM machine in Lightroom. I've verified the same file opens just fine on a Windows Intel machine.

 

  • Z8 with up-to-date firmware, taking photos with "raw only"

  • Lightroom v7.4.1 (most up to date according to the creative cloud updater)

  • by-hand insta;led Adobe Camera RAW (v16.4 from AdobeCameraRaw_arm64_16_4.exe)

  • Downloaded and installed Nikon's RAW plugins, though I do not think those are ARM (and I can't tell if they are working).

I see:

  • In lightroom's review for import window a warning icon for each NEF file with a mouse-over message "this file does not contain a supported format (or it might be damaged).

  • The icons in windows show up with the complete picture

  • Opening the pictures in windows at first shows the proper image but then goes all technicolor lines on me.

  • I see same error in Adobe's DNG converter and photoshop (both of which have ARM versions)

I suspect the windows and LightRoom issues are distinct, but thought I'd post them here. This is a new machine, fresh install. So it is possible I've forgotten to install something. And this workflow does work on my large AMD based computer.

 

It could be not all the software is in place for the RAW format for lightroom, but it would be nice if something gave me a clue of what to look at to find that!

I had the same issue with my Nikon Z8 and the new Microsoft Surface Pro 11 and was in trouble as I could not save my pictures while I was travelling. Back home again I was able to save and upload the pictures to Lightroom on my MacBook. I tested different settings on the Z8 and what seems to help is what  somebody else has suggested here to switch to lossless compression for the NEF files. I still wonder why such an error was not detected earlier by MS and Adobe.

I have the same issue - it works if you use lossless compression for the RAW files. It seems that there is a licence missing for the compression library used here. But to switch to lossless compression make the files huge ...

That is good news (that it is just a licensing issue). Oddly, it is Intel vs ARM, but that shows, I suppose, the state of the industry. It would be nice to have some official mention of this on their bug pages somewhere.

    This is your clue. 

    That Windows shows an intact thumbnail (from the embedded preview in the. raw file) and won't open the file points towards a data corruption. 

    How are you getting your files from the memory card to the local machine?

I'm dragging and dropping them, as I do on the Intel based windows machine, from camera or directly from the card with a card reader (i've tried both).

 

My impression is the plug-ins that windows uses and Adobe uses to look at the NEF files were different. Hence the camrea raw package from Adobe. Is that not the case?

The Camera Raw Package is irrelevant to the operation. Neither Windows nor LIghtroom use the Camera Raw plugin you've installed. 

Load a raw file to lightroom.adobe.com and allow it to sync to your 7.4.1 installation.  What happens?
