Note: The installer is not code-signed. Windows SmartScreen and your browser may show a warning — click "More info" then "Run anyway" (or "Keep" in the browser).
Where does it save? The file downloads to your default Downloads folder. Your browser's download bar shows the file — click it to open the folder. Downloads use a fast Cloudflare proxy; if it fails, the page offers a direct GitHub link.
