That’s how it works. In theory (except for the flaky Activate button) this lets non-Administrators autoupdate. Putting updates directly in Program Files may require a Windows prompt for an Administrators password.
Think of the Program Files version as a launcher for the latest update. If there is none, it starts its version.
Either way, there are parent and child processes. You can view this in Task Manager or Process Explorer.
Getting information about your setup About → System info will show these versions. 2.0.5.1 is your Base.
* BaseVersionName : (should say 2.0.5.1 for you)
* ServerVersionName : (should say 2.0.6.3 for you)`
[SOLVED] Is it ok that I see 5 processes of Duplicati in Windows Task manager? adds a TrayIcon pair too.
