Click More info, and verify that the publisher shown by Windows is Nikhilesh Vaidya and that you downloaded MailSeer from this SearchSeerAI site or the official GaussEuler/MailSeer-Releases GitHub release. Then choose Run anyway to continue installation.

Do not proceed if the publisher is missing, different, or the installer came from another source.
