The driver install errors showed up during the install process. I went in later and used device manager to update the driver manually. It still refused to install drivers and reported errors. I tracked the problem down to a code signing problem with the file usbblstr.inf. Apparently the certificate was not timestamped properly. Is an updated driver package available?
The Signtool utility shows me the error below.

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

Hi SVigil,
Yes, it needs to be at the moment. You may follow the method as listed below to update the digital signature certificate.

Thank you. I will resort to buying Blaster II cables if I must. But is there a similar certificate fix for the USB Blaster Cables? I already purchased two USB Blaster for $600. The current drivers that are causing the problem came from the Quartus Programmer 20.1.1.720 downloaded last week. Does this release contain the most up to date drivers?

Unfortunately, your first link does not have the driver for download on that page, just instructions for installing it. You still have to download the full Quartus to get the driver, which is weird.

Yes, first link is meant to guide user on installing the driver. Driver for USB Blaster can be found in the 2nd link.
Yes it is. But for now we will still need to apply the guide in installing the USB Blaster driver if there is any failure.

Thanks Bruce. Now the problem I'm having is the patch will not install. I'm trying to fix a stand alone programmer installation, and it says there is no stand alone programmer install in any directory I try. See attached screen shot of the attempt of trying the directory with the main executable in it. Can you tell me which I need to select?

I don't know if it was selected correctly, because I don't know what is the correct directory to select. Can you please tell me which directory I'm suppose to select? I tried the one shown in the screenshot I provided several times.

Or actually better yet can I do this without using the patch like the below link suggests for the blaster II cable?
Link: Why does the Intel® FPGA Download Cable II driver installation fails on Windows* operating system?
I just need the equivalent updated .inf and .cat files for the Blaster I cable and I can try to substitute them like the Blaster II procedure. Can you send these files?
