I followed the instructions in the guide. It did not fix the problem. I still get an error when I attempt to update the driver.

The instructions provided an link to and updated driver package for the usb-blaster-ii device. I have a plain usb-blaster device. Is there some way to get a a correctly signed driver package for this device

    Ok I figured out a painful workaround. I downloaded and installed version 18.0 of quartus prime lite.

    At the end of the installation a dialog comes up allowing you to specify whether you want to install drivers or shortcuts. Say no to everything and exit.

    Launch device manager

    Navigate to usb-blaster device

    Right click and select "update driver"

    Select browse by computer for driver software

    Select the v180.0 folder <installpath>\18.0\quartus\drivers and click next

    Driver should install correctly.
