CRITICAL: Pre-Installation Steps
To ensure the software and interface work correctly, you must follow these steps before installation. Using this software with an active internet connection can cause the interface to become blocked.
- Turn off Antivirus: Temporarily disable your antivirus software (AVG, McAfee, etc.).
- Disable Windows Defender: Temporarily disable Windows' built-in real-time protection.
- Block VCDS in Firewall: Add a rule to your Windows Firewall to block the main VCDS application from accessing the internet. Do not turn off the entire firewall.
Installation & Activation Guide
- Run the installer `VCDS-Release-25.3.0-Installer.exe`. Follow the on-screen steps. If your system is 64-bit, ensure the 32-bit to 64-bit drivers are installed.
- When installation is complete, DO NOT run the VCDS software yet. If a shortcut was created on your desktop, delete it.
- Copy the loader program, `VCDSLoader.exe`, from the archive into the VCDS installation folder (usually `C:\Ross-Tech\VCDS\`).
- Create a new shortcut on your desktop for the `VCDSLoader.exe` file you just copied. You must always run VCDS using this loader.
- Connect your VCDS cable to the PC for the first time. Wait for the drivers to install.
- Run `VCDSLoader.exe` from your new shortcut. Click "Options," then go to the "Port and Protocol Options" tab. Click the "Test" button to check the interface. Once it shows "Status: OK," click "Save".
- Close the software, connect the cable to your car, and run `VCDSLoader.exe` again to begin diagnostics.
