How to Install FORScan on Windows (Step-by-Step Guide)

Windows is the full version of FORScan. Use it if you want to read and clear error codes, see live data, run tests, or eventually change vehicle settings such as lights, tyre size, or comfort options.

If you only want phone-based diagnostics, Android or iPhone can be convenient. If you want to change vehicle settings, start with Windows.

What you need before installing FORScan

• A Windows laptop or PC.
• A compatible FORScan adapter.
• Your Ford, Lincoln, or Mazda vehicle nearby.
• Internet access to download FORScan and, if needed, request an Extended License.

Step 1: Download FORScan from the official site

Download the Windows installer only from the official FORScan download page. Choose the current Windows release unless you have a specific reason to test a beta version.

Save the installer somewhere easy to find, such as your Downloads folder. If Windows or your security software raises a warning, do not bypass it automatically—confirm that the file came from the official FORScan site first.

Step 2: Install the program

1. Open the downloaded installer.
2. Follow the setup prompts. The default installation location is normally fine.
3. Finish the installation, then open FORScan.

You do not need to connect to the vehicle just to install the program.

Step 3: Set up your adapter

Your adapter is the small device that connects the laptop to the vehicle’s OBD-II port. Some USB adapters install automatically; others need a driver from the adapter maker. Bluetooth and Wi-Fi adapters need to be paired or connected in Windows before FORScan can use them.

• USB: connect the adapter and install its driver if Windows asks for one.
• Bluetooth: pair the adapter in Windows first, then use the connection created by Windows.
• Wi-Fi: connect the laptop to the adapter’s Wi-Fi network before opening FORScan.

For configuration work, a stable wired adapter is the easiest starting point. See our adapter chooser for the practical differences.

Step 4: Connect to the vehicle for the first time

1. Plug the adapter into the vehicle’s OBD-II port, usually below the dashboard near the driver’s seat.
2. Turn the ignition on as instructed by your vehicle and FORScan; do not start the engine unless a procedure calls for it.
3. Open FORScan and select the correct connection type if it asks.
4. Let FORScan read the vehicle information and modules before attempting any change.

What is the Extended License?

The standard Windows version is enough for many diagnostic jobs: reading and clearing error codes (DTCs), viewing live data, and running supported tests. The Extended License is for additional service functions and configuration changes.

You are more likely to need it if you want to change settings—such as lighting behaviour, tyre size, or module configuration. You do not need it merely to install FORScan or read a code. FORScan currently provides a free two-month Extended License trial through its official site.

If FORScan cannot connect

• Check that Windows sees the adapter before opening FORScan.
• Confirm the ignition position and that the adapter is fully seated in the OBD-II port.
• For Bluetooth or Wi-Fi, make sure Windows is connected to the adapter—not another device or network.
• If FORScan reads only some modules or disconnects, stop before changing settings and check whether the adapter supports the Ford networks your vehicle needs.

What to do next

Start by reading the vehicle for error codes and live data. Once the connection is stable, you can decide whether you need the Extended License for a specific change. For a plain-English guide to diagnostics, configuration, and programming, read Which FORScan adapter do I need?
