P: Cannot Send Files from Lightroom to Photoshop on Surface Laptop 7 (ARM)
Issue
When I use the "Edit in Photoshop" command from Lightroom, Photoshop launches as expected, but then I receive the following error message:
"Could not open Photoshop"
The file never opens in Photoshop.
My Setup
-
Device: Microsoft Surface Laptop 7th edition (ARM/Snapdragon X Elite)
-
Operating System: Windows 11 Home/Pro ARM64 (latest version)
-
Photoshop: Latest version from Creative Cloud (ARM version)
-
Lightroom: Latest version (cloud version, not Classic)
-
Creative Cloud: Up to date and signed in
What I Have Tried
-
Photoshop and Lightroom are both up to date.
-
Creative Cloud is up to date and I’m properly signed in.
-
I’ve logged out/in, reinstalled the apps, and restarted the computer.
-
I’ve tested exporting images as TIFF/PSD from Lightroom and manually opening them in Photoshop – this works.
-
I've checked that both apps have full file/document access in Windows privacy settings.
-
I’ve tried changing the file format and target path in Lightroom’s external editing preferences.
-
The error occurs regardless of file format (RAW, JPEG, etc.)
Suspected Cause
I suspect this may be related to how Lightroom sends temporary files to Photoshop in the ARM environment – potentially an issue with file encoding, format, or temporary paths that Photoshop ARM cannot process correctly.
What I Need Help With
I would appreciate assistance with:
-
Identifying whether this is a known issue with ARM-based Windows devices
-
Any possible workaround or ETA for a fix
-
Information on what logs I can provide to help with troubleshooting
Thanks in advance!
