#Installation

Download the latest installer for your platform from the releases page.

Already installed? See Updating software for automatic and manual update options.

#Windows WebView2

On Windows, if you cannot install WebView2 due to network issues, you can install WebView2 offline.

#macOS — unsigned app (Gatekeeper)

Duckling for macOS is not notarized/signed, so Gatekeeper blocks the first launch with a “damaged” or “cannot verify developer” warning. To allow it, remove the quarantine attribute:

sudo xattr -rd com.apple.quarantine /Applications/Duckling.app

Substitute the path where you actually placed the app (.app bundle) if it is not in /Applications.

The -rd flag rewrites the attribute recursively, clearing it on the bundle and every file inside it. You only need to run this once per downloaded copy. Alternatively, right-click the app in Finder and choose Open to approve it.

#Note on the installation path

When selecting an installation path, choose an empty folder or create a new one. Do not place data files in the installation path and avoid selecting a non-empty folder.

During uninstallation, if you choose to clear data files, the entire folder is deleted — including files that do not belong to the software.

#Q&A

On Windows, DuckDB requires the Microsoft Visual C++ Redistributable at runtime. If DuckDB-related features misbehave, this dependency is the likely cause — download and repair it. See Building DuckDB on Windows.
