The Windows desktop app now stops its background service before it installs or uninstalls, so reinstalling no longer fails with a file-in-use error. The backend runs as a separate process that could keep running after the app was closed or uninstalled, and because Windows locks a running program on disk, the next install could not replace it until you ended the process by hand in Task Manager. The installer and the uninstaller now end that process for you first, so a reinstall just works.

The backend service is also renamed from openestimate-server to openconstructionerp-server, so the whole app carries one name. An upgrade from an older version still stops the old process by its former name, so nothing is left running behind. Your data folder and settings are untouched.
