After updating from the 2019 version to the latest one (on Win8.1, German) Duplicati doesn’t start any more.
In detail: I installed the update from the GUI and then clicked on “activate”. This was followed by “connection to server lost, try again in … seconds”. Since there was no way to get rid of this pop up after several futile attempts to reconnect (to which server?), I closed the brower tab.
When trying to start again through my ususal shortcut (“C:\Program Files\Duplicati 2\Duplicati.GUI.TrayIcon.exe”) nothing happened.
Then I ran the same command from a command prompt and got a huge number of errors, but my prompt only returned after killing execution with CTRL+C. Redireting the messages into a file failed, so I copied them manually (hence the odd line wrap).
Some excerpts of the messages:
“Unexpected error: System.IO.FileLoadException: Die Datei oder Assembly “Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed” oder eine Abhängigkeit davon wurde nicht gefunden.” [i.e.Json file or dependencies were not found]
System.Reflection.TargetInvocationException: Ein Aufrufziel hat einen Ausnahmefehler verursacht.” [i.e. target call caused an exception]
… followed by a call stack.
For more details see log attached (I can translate more text if required) DuplicatiCrash.zip (1.5 KB) .
Any ideas what’s wrong here? Is there a way to revert to the previous version?
BTW I successfully updated my installation on a Win10 Laptop in the same way (but I don’t recall clicking “activate” to get it working OK)
