    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.

    Yuan,

    I had this same issue with the USB blaster cable, and found the below work around. It seems there is a signature security issue with the usb blaster driver. My question is, if I buy a USB blaster II cable for $225 does it have a proper signature in the driver? My IT department at my company does not want to install a driver that doesn't have a signature.

    Solution: You first have to disable driver signature enforcement. This is the sequence:

    1 - Go to windows 10 settings and search for "advanced startup options" 2 - Under Advanced startup, hit "Restart now" 3 - After a moment, you'll get a "choose an option" screen - choose "Troubleshoot", then "Advanced options", then "Startup Settings" 4 - You'll get a screen telling you what you will be able to change and a single "Restart" button - press it. 5 - If your boot drive is BitLocker encrypted, you'll need to enter the recovery key (press return, enter the key in the text box then hit return again - it took me three goes to realize I had to hit return before I could enter they key !) 6 - You'll be given a menu of options, number 7 disables driver signature enforcement 7 - When the PC restarts, use Device manager to update the drivers - this time you'll get a warning about the signature, but they install fine. 8 - When you've finished, restart normally to re-enable signature enforcement
