Welcome to the forum @frapox
Release: 2.1.0.2 (Beta) 2024-11-29
Example change with a different context (if you have a custom database path, use it instead).
The GUI password is unrelated, although some people might opt to use one password for both.
Try again after you’re sure you have a GUI password in the Windows service and know what it is.
Cannot make 2.0.9 work as Windows Service has a similar symptom, but I “think” you have its fix.
Further comment would have to come from the developer, but please at least set up a password.
