I cannot update LR to a version which I have on m laptop. Laptop has 15.4, home computer has 15.3.1 and Creative Could is not capable to find the V15.4 and to update my main version. Thus a catalog exported with photography on the road cannot be imported to the main workstation.

We are investigating a reported issue with the new duplicate deletion feature in Lightroom Classic. If you've already updated to the latest version, we recommend not using the "remove duplicates" action until we can confirm and resolve any issues.

Lightroom Classic most recent update, 15.4 is not available to me when I try to update to latest version. When I click on updates, it show that the latest is 15.31.

Thanks. Of course problems can happen, what is wrong is the cloak and dagger. I was even contacted by support, someone took “control over my workstation” and than basically said “do not worry, it is a backend problem, it will be solved soon.” So your own tech was not aware what is causing the issue. And consequently he could not explain what caused the issue. He also could not tell me how to “downgrade” LR back 15.3.1 so that I can import the catalog to my the workstation.

Is there a way to downgrade my catalog as I can’t access it as it was upgraded to 15.4 already.

I’m afraid there isn’t a way to downgrade a catalog, other than restoring the pre-upgrade catalog.

If the catalog already upgraded to 15.4, then you’ve already got it downloaded, surely? Or perhaps it downloaded on another machine? Which operating system do you use? I heard of one macOS user copying the 15.4 app from their laptop to their desktop, although I can’t be sure how safe that is.

I wouldn’t expect it to take long before 15.4 is available again, likely as an urgent 15.4.1 release. They’ll be pulling out all the stops to get this sorted asap.

I just upgraded to 15.4 before reinstalling my computer. Then after install only got 15.3.1 as an option. Stuck for now, thankfully not life threatening...just annoying. Will just keep checking for updates.Thanks for your reply.

I believe the 15.4 download has been temporarily pulled due to discovery of a bug that could result in data loss. They’re working to get a fix out ASAP, but better to make it unavailable for a short time than for someone to lose precious original photos.

I don’t think that’s it. I also have a M1 Macbook and it updated to version 15.4 just fine. I was able to copy the app from the macbook to my M4 Mac Studio. It runs ok that way, although it still doesn’t show up in Creative Cloud app.

That's a good workaround. When did you update the MacBook? There’s probably a timing factor involved, as this is a developing situation, and availability will likely depend on when the CC app last refreshed.
