Key driver install fails

Modified on Wed, 13 Jun 2018 at 11:06 AM


"Unknown device" in the Windows Device Manager, or "Driver installation failed" error message when inserting Key on Windows Vista, Windows 7, Windows 8 and Windows 10


Most likely caused by:

  • 3rd party driver or software installation reinstalling new versions over Windows drivers or corrupting registry
  • A random bug with Windows causing automatic driver detection to fail
