Duplicati.GUI.TrayIcon.exe - System Error

Uncategorized
1

The following error is randomly occurring with Duplicati 2.4.1.0 - 2.4.1.0_stable_2026-10-29 on Windows 11, which is up to date with maintenance. The error occurs generally during startup, but can happen during a backup:

Thanks for the report. That dialog is not one Duplicati produces; it is the Windows “hard error” box for an access violation (0xC0000005) in native code inside the TrayIcon process. Because it happens outside the .NET runtime, nothing about it ends up in Duplicati’s logs, so I need a bit more from your machine to narrow it down.

Could you post the following?

  1. The Event Viewer entries for the crash. Open Event Viewer, go to Windows Logs → Application, and look for entries from “Application Error” (and possibly “.NET Runtime”) with Duplicati.GUI.TrayIcon.exe at the time of the dialog. The “Faulting module name” and “Fault offset” lines are the important ones.

  2. Whether it still happens if the tray icon does not host the server. On Windows the tray icon runs the whole backup engine in the same process, so the crash could be in the engine, in the tray icon layer, or in a DLL another program injects. To separate those, start the server on its own, then run the tray icon against it:

"C:\Program Files\Duplicati 2\Duplicati.Server.exe"
"C:\Program Files\Duplicati 2\Duplicati.GUI.TrayIcon.exe" --no-hosted-server --hosturl=http://localhost:8200

If the dialog then names Duplicati.Server.exe, the problem is in the engine; if it still names TrayIcon.exe, it is in the tray layer.

  1. Whether disabling any other screen-capture, overlay or security tools that hook into running programs for a while changes anything. Those tools load their own DLLs into other processes, and that is a common source of this exact dialog.

With the faulting module name I can dig a bit further to see what causes it.
