This usually happens because the browser's 'silent blocking' mechanism kicks in, hiding the installer as a potential risk. The download hasn't actually failed—the file is typically quarantined in the browser's secure recovery area. You can retrieve it by pressing Ctrl + J. Three steps to recover the blocked installer: 1. Open the management page: Press Ctrl + J (or manually go to the browser's download history page). 2. Restore the file: Locate the GameBuff installer marked as 'Blocked' or 'Unsafe' in the list, then click 'Restore' or 'Keep' below it. 3. Adjust security settings (if the issue persists): If the file keeps getting auto-deleted, go to browser settings > Privacy and Security, temporarily turn off 'Enhanced Protection Mode', and re-enable it after the download completes.
