2. Extract it to a folder. If the folder contains setup.exe or install.exe, run it as administrator.
3. If there is no installer, right-click the device in Device Manager, choose Update driver, then "Browse my computer for drivers", select the extracted folder (leave "Include subfolders" ticked) and click Next.
4. Restart the computer and check that the device no longer shows a yellow warning sign in Device Manager.
