The Desktop edition uses a newer cross-platform UI; WPF is the classic, stable edition with a familiar Windows interface and workflow. Start with Desktop if this is your first install, or choose WPF if you prefer the interface you already know.
Package format: Both downloads are ZIP archives. Extract the entire archive before opening the installer; do not run it from the archive preview. After installation, launch the client from your system's app list for easier updates and removal.
Switching editions: The two editions have different layouts, and menu names and settings locations may change between releases. Back up subscription URLs, routing rules and custom settings before switching; do not assume the other edition will read the same configuration directory. Run only one client instance at a time to avoid conflicts with local listening ports or system proxy settings.
