⚠️ Important Security Notice

Before downloading, please note that FortiClient 6.4.6 is an older version. The 6.4.x branch has reached its End of Life (EOL) or "End of Engineering Support" status. This means it no longer receives security updates or bug fixes.

If you are required to use this specific version for compatibility with a corporate VPN server, proceed with the download below. However, if you are the administrator or have a choice, it is highly recommended to use FortiClient 7.x (currently v7.2 or v7.0) for better security and performance.

9. Who Should Download 6.4.6 Today?

✅ Download if:

  • Your employer specifically requires FortiClient 6.4.6.
  • You are running FortiGate firmware 6.4.x and cannot upgrade.
  • You need a legacy driver for an older Windows 10 LTSC build.

❌ Do NOT download if:

  • You are a home user looking for privacy VPN.
  • You need security features (antivirus/web filter).
  • You want the latest security patches.

Installation Process

  1. Run as Administrator: Right-click the downloaded FortiClientSetup_6.4.6.xxx.exe and select Run as Administrator.
  2. Language Selection: Choose your language and click OK.
  3. License Agreement: Accept the EULA. Unlike newer versions, 6.4.6 does not aggressively push telemetry.
  4. Installation Type:
    • Typical (Recommended): Installs VPN, Web Filter, and AV. You can disable unwanted modules later.
    • Custom: Allows you to uncheck "Anti-Malware" and "Web Filter" to force a VPN-only mode. For pure VPN use, choose Custom and select only VPN and Solver.
  5. Installation Path: Leave default C:\Program Files\Fortinet\FortiClient.
  6. Click Install: The process takes approximately 2 minutes.
  7. Reboot: The installer will prompt a reboot. Do not skip this—kernel drivers require a restart.

Method 3: Direct ISO via FortiClient Fabric Agent

Enterprise users often push 6.4.6 via the FortiClient EMS (Management Server). If you are an end-user in a company, your IT department likely hosts the 6.4.6 msi on an internal network share.
