Finding a direct link for a "FortiClient VPN 6.4 offline installer" can be tricky because Fortinet typically distributes an online installer (a small stub file) that downloads the full package during execution.
To get the offline installer, you generally need access to the Fortinet Support Portal, but there is a common workaround to extract the full .msi or .exe from the online installer. Method 1: Extract from the Online Installer
This is the most reliable way to create your own offline installer without a support account.
Download the Online Installer: Get the standard FortiClientVPNOnlineInstaller_6.4.exe from the Fortinet Product Downloads page.
Run the Installer: Start the installation. The tool will begin downloading the full package (usually around 80-100MB).
Locate the Temp Files: While the installer is running (or after it finishes downloading but before you click "Install" or close it), open your Windows Temp folder: Press Win + R, type %TEMP%, and hit Enter.
Find the Setup File: Look for a folder with a randomized name (e.g., 7E...) or search for FortiClient.msi.
Copy the File: According to experts on YouTube, you can also check the installation logs in the Temp folder for a "cached" file path. Copy the .exe or .msi to a safe location (like your Desktop). This is now your offline installer. Method 2: Fortinet Support Portal (Official)
If you have a paid license or a corporate account, you should use the official route to ensure the file is untampered. Log in to the Fortinet Customer Service & Support portal. Navigate to Support > Firmware Download. Select FortiClient as the product. Browse the folder structure: Windows > v6.00 > 6.4 > 6.4.x.
Download the file labeled FortiClientVPNSetup_6.4.x_x64.exe (this is the full offline installer). Method 3: Third-Party Repositories (Caution Required)
Some community sites and IT repositories host the offline installers.
Warning: Only download from reputable sources. Always verify the digital signature of the file by right-clicking the .exe > Properties > Digital Signatures. It should be signed by Fortinet, Inc. forticlientvpnonlineinstaller-6.4 offline installer
Sites like FileHorse or MajorGeeks sometimes host older versions, but version 6.4 may be harder to find due to Fortinet's licensing changes for newer versions. Summary of Version 6.4
Version 6.4 was the last version where the "VPN-only" client was widely available for free without requiring a FortiClient EMS (Enterprise Management Server) license for basic features. Newer versions (7.0+) often nag users for a license or have limited features unless managed by a server.

The "online installer" is a small file that downloads data during installation, whereas the offline installer contains all necessary files in one package. 1. Download the Offline Installer
Because Fortinet restricts direct public downloads for older versions, you generally need a support account to access them: Log in to the Fortinet Customer Service & Support portal. Navigate to Support > Firmware Download in the top menu. Select Product: Choose FortiClient from the dropdown list.
Select Version: Navigate through the folders: Windows > v6.00 > 6.4 > 6.4.x (choose the latest patch).
Identify the File: Look for the .zip or .exe file that is significantly larger (usually 50MB+) rather than the 3MB online installer. This information is verified by experts on the Fortinet Community. 2. Prepare the Installation Media
Transfer: Copy the downloaded file to a USB drive or external hard drive.
Extract: If you downloaded a .zip file, extract its contents to a folder on the target offline machine. 3. Run the Installation
Launch: Double-click the installer (e.g., FortiClientVPNSetup_6.4.x.exe). License Agreement: Read and accept the terms to proceed.
Setup Type: Ensure you select the components you need. For most users, the default VPN-only setup is sufficient. Convenience and Simplicity : It eliminates the need
Finish: Once the progress bar completes, click Finish. You may be prompted to restart your computer. 4. Configuration (Post-Install)
Once installed, you will need to manually configure your VPN settings since the machine is offline: Open FortiClient and click Configure VPN.
Enter your Connection Name, Remote Gateway (server IP/address), and Port.

The FortiClient VPN 6.4 offline installer is a critical tool for IT administrators and remote workers who need to deploy Fortinet's secure endpoint connection software without relying on a live internet connection during the installation process. While Fortinet primarily promotes an "online" or "stub" installer that downloads necessary files on the fly, the offline version (typically an .exe or .msi file) is preferred for bulk deployments and environments with restricted or slow internet access. Core Functionality and Features

Please retry." | Corrupted cache or MITM attack. | Offline installer bypasses remote hash check. | | "Cannot reach update.fortinet.net" | DNS filtering. | Offline installer requires no DNS. | | "Installation rolled back at 80%" | Online installer timed out. | Offline installer reads from local disk, no timeout. |
