Download the driver installation file, saving it to (the downloads folder or desktop on) your hard drive. After the download has completed, find the file that was downloaded, and double-click it to start the installation. Close the web browser at your next opportunity, and interact with the driver installation wizard to complete the driver installation. It is usually best to select the default options during driver installation.
Please reboot after the driver installation has completed successfully.
