Error messages: The database has version 12 but the largest supported version is 11

HI
After updating now I get this error

Duplicati.Library.Interface.UserInformationException:
The database has version 12 but the largest supported version is 11.

This is likely caused by upgrading to a newer version and then downgrading.
If this is the case, there is likely a backup file of the previous database version in the folder C:\Windows\system32\config\systemprofile\AppData\Local\Duplicati.

what did you do exactly, updated to what from what, how did it go, did you try to downgrade or not ? this seems to not make sense at all.

Windows server environment with active duplicate service. We have the program set up in Italian. The update request for new version appeared. Updated. First backup correct. Successive backups corrected. If we restart the server we get that next backup with error.

More information. During the update we are forced to stop and restart the duplicate service manually.

This is looking like a case of mixing Duplicati as a service and Duplicati as an application. Maybe your did the upgrade with Duplicati as an application. This can happen when Duplicati has been setup as a service, but the tray icon is still used to start Duplicati and it is starting Duplicati as an application for the current user. This is showing as the port 8300 (instead of 8200) in the browser URL.

When setting up Duplicati as a service, I usually disable the tray icon and create a shortcut for Duplicati with a link to http://localhost:8200, to manage the service-launched version and never start the user mode Duplicati.

Edit: the start mode can be seen also in the ‘About…’ function / System Info / StartedBy

If you find StartedBy on that page, you can also look at BaseVersionName just below it.
Given how you updated, it’s normal for it to be at prior version, but ServerVersionName
slightly above should show new update which was found then launched by base version.

You can also look for your update in below locations to see how you might have updated:

If your update is in the proper spot, it’s possible it got damaged. Look for new files inside.
Sometimes things such as log files get in the update. Changes cause it to fail verification,
meaning base version doesn’t run it, but runs the last “good” one, which might be 2.0.6.3.

Any idea why you had to do so, and where in the stated sequence you did that? Sequence:

Is there another restart, per “More information” post, or is it just commenting on one above?
