If you work remotely or need secure access to your company's network, FortiClient VPN is probably on your must-install list. I've set this up more times than I can count, and honestly, it's very simple once you know the steps. In this guide, I'll tell you through the complete process.
Things Require Before A Start
Before knowing about an installation, make sure you have a few things ready.
- First, you'll need administrator access on your Windows PC. Without it, the installation simply won't work.
- Second, know your VPN connection details from your IT department which includes the server address, your username, and password. Trust me, having this information beforehand saves a lot of back-and-forth later.
Your computer should be running Windows 10 or Windows 11. While FortiClient technically works on Windows 7, most organizations are moving away from it. Also, check if you have any other VPN software running. Sometimes these programs clash with each other, so it's best to disable or uninstall competing VPN clients before you proceed.
Here's How to Download FortiClient VPN
Here's where many people get confused—there are multiple places to download FortiClient, and you need to choose the right source. The safest bet is always the official Fortinet Support Portal at support.fortinet.com. However, many companies provide their own download links or host the installer on internal portals. If your IT department gave you a specific link, use that one instead.
When you reach the download page, you'll notice different versions available. Don't just take the newest one automatically. Check with your IT team first because they might want you on a specific version that matches your company's setup. As someone who's dealt with compatibility headaches, I can't stress this enough—version is important.
You'll typically see two package types: the standalone VPN-only version and the full FortiClient package with endpoint management features. For most remote workers, the VPN-only version is sufficient and downloads faster. The file size is usually between 100-200 MB, so make sure you have a stable internet connection.

Step by Step Guide for FortiClient Installation
Once your download completes, locate the installer file in your Downloads folder. It'll usually be named something like "FortiClientSetup.exe" or "FortiClient.msi."
Here's an important tip: Don't just double-click it. Instead, right-click the file and select "Run as administrator." This ensures the installer has proper permissions to make necessary system changes.
Windows will likely show you a User Account Control prompt asking if you want to allow this app to make changes. Click "Yes" to proceed. The installation wizard launches, and you'll see a welcome screen. Click "Next" to begin.
The license agreement appears next. I know most people skip reading these, but if you're installing this for work, your company's IT policies might require acknowledgment. Click "I accept" and move forward.
Now you'll choose your installation type. The "Typical Installation" option works perfectly for most users. It includes VPN functionality and essential components without overwhelming you with choices. If you have specific requirements or know exactly which features you need, the "Custom Installation" option lets you select individual components.
The installer asks where you want FortiClient installed. The default location (usually C:\Program Files\Fortinet\FortiClient) works fine for most situations. Unless you have a specific reason to change it, just click "Next."
Review your choices on the summary screen, then click "Install." The installation process takes a few minutes. You might see additional security prompts from Windows Defender or your antivirus software. Allow FortiClient to proceed—these prompts are normal when installing network software.
When the progress bar reaches 100%, you'll see a completion screen. Click "Finish" to exit the installer. FortiClient typically launches automatically, but if it doesn't, you can find it in your Start Menu.
Now Set Up Your VPN Connection
With FortiClient installed, the next step is configuring your connection. Open the application and look for the VPN section—it's usually marked with a globe or shield icon on the left sidebar.
Click the "+" button or "Configure VPN" option to create a new connection. You'll need to fill in several fields with the information your IT department provided. Give your connection a descriptive name like "Work VPN" or "Company Network"—something you'll recognize easily.
In the "Remote Gateway" field, enter your VPN server address. This might be a URL like vpn.yourcompany.com or an IP address. Be careful here—one wrong character and your connection won't work.
For most organizations, you'll select "SSL VPN" as your connection type. This provides secure, encrypted access through standard web ports. Leave the port settings at their defaults unless your IT team specified otherwise.
Under authentication, you'll typically choose "Username and Password." You can save your credentials if you're on a trusted device, but if you're using a shared computer, enter them manually each time for security.
Testing Your Connection
Before declaring victory, test your VPN connection. Click the "Connect" button in FortiClient. If everything's configured properly, you'll see a connection status indicator turn green, and you'll be connected to your company network.
If the connection fails, don't panic. Double-check your server address and credentials first—these are the most common culprits. Make sure your firewall isn't blocking the connection, and verify that your internet connection is stable.
In Conclusion
FortiClient VPN installation isn't very difficult, but attention to detail is really important. Get your information straight from IT, download from official sources, run the installer with admin rights, and configure carefully. Once it's set up, connect to your work network becomes easy as you click a button.
If you run into issues beyond basic troubleshooting, reach out to your IT support team. They have access to server logs and can see problems you can't diagnose from your end. With FortiClient properly installed, you've got secure, reliable access to your work resources from anywhere.
