P: (MS App Store Version) Message: Some photos were not added. Unable to copy file.

@reuben5C68 I found that using the web page version: lightroom.adobe.com always works (even during the days when any installed app didn't) so I suggest that you try it out. You may not be satisfied with the import speed (since it is a webpage, during the import, actual upload will be running) but I found it acceptable because I only upload 36-38 (one roll of film scanned) photos a time.

I'm on Windows 11 build 22000.675

The idea that an OS upgrade made the difference make sense except - I was uploading files and getting the 3 at a time reponse. All I did in between was exit Lightroom and re-enter. Which is what I would do to get it to load 3 more files. And...it suddenly took all the uploads I fed it. No updates in between and definitely no reboot. It's been working ever since.

Steph245..., please see the suggestion from Rikk in the green box near the top of the page to download Lightroom from www.adobe.com instead of the Microsoft Store. 

Donna H, that's great news that this started to work for you recently. I am wondering if this could be due to an update of the OS. Would you mind telling us what version of Windows you're on? To find out, 

1. Click the Windows Start button in the lower left

2. Type "System Info" and hit Enter

3. See the secon line ("Version") in the System Information app that appears. For example, mine says "Build 22000"

The problem seems to have miraculously fixed itself. I tried all the recommended solutions and nothing worked. My version was fully updated. Even reloading the software. I finally gave up for a while because I was in the middle of a project and needed to just get the pictures uploaded. I ended up importing hundreds of photo's 3 at a time and then weeks later ...it worked. Very strange because I was uploading some pictures and it failed (as usual), I closed the software and reopened to try for 3 more and it took all of the pictures. Since then it has been just fine. Weird but since it's working, Im happy.

Hi,

I'm afriad the described fix did'n't work for me. LR is of the latest version (MACos) and so is the Creative Cloud app. Of 66 files (RAW) 11 will not be imported, whatever I do. I've tried it several times, including storing these particulary files directly on my hard drive and try to import them from there... the other 55 were important right away, without any issues.

Hope (another) fic will be available soon.

Thanks in advance!
