Windows

  1. Open the Download page and choose the Windows installer.
  2. Run the downloaded .exe and follow the installer instructions. Approve a permission prompt only if you trust the official installer.
  3. Open AeroMailer from its desktop or Start menu shortcut.

macOS

  1. Download the macOS .dmg from the same page.
  2. Open the disk image and run AeroMailer Setup when included so the app and ClamAV scanner can be installed. Follow the instructions in the official package.
  3. Launch it from Applications.

Attachment scanner setup

The setup process can download ClamAV online to keep the installer smaller. Internet access is required. After installation, open Settings → Security and confirm the scanner and virus definitions are ready. Use Install ClamAV to repair an interrupted setup and Update virus definitions for current signatures. Merely enabling Attachment Scanning does not mean the scanner is ready.

First launch

Select a language, read the license agreement, scroll to the end, and accept to continue. Declining closes the app. Activate with your license email and key. End users do not need Node.js, Rust, or a database server.

If the operating system blocks an installer, verify its origin and contact support. Do not disable security protection or use an unofficial modified installer.
