Installing the 64-bit Driver on Windows

While the KKL VAG-COM 409.1 interface offers a budget-friendly solution for VAG vehicle diagnostics, installing the correct drivers, especially on 64-bit Windows systems, can sometimes pose a challenge. Follow these steps to ensure a successful installation:
