USB-Blaster classic driver certificate expired

We are using Quartus 20.1.1 LITE. The usb blaster drivers certificate has expired, so driver installations fail. We can't use USB Blaster II. Looking at the threads it seems Quartus 21.1 has this fix...

Aiman,

The certificate issue you posted the link for is exactly the problem. However our issue is, we don't have any Blaster II cables for our teaching labs. We can only use Blaster classic (version 1) drivers. However, 20.1.1 LITE still has blaster version 1 certificate expired. There hasn't been any updates to Quartus LITE. We are using the LITE version of Quartus.

In doing some searching, we are using Terasic boards for our classes. I found this link from them:

http://www.terasic.com.tw/wiki/Windows_encountered_a_problem_installing_the_drivers_for_your_device

this specifically addresses the problem for USB blaster classic/ver1 drivers. This does allow the driver installation to complete. I checked the certificate from them and its not expired.

I have a few questions:

1. Is the Quartus team going to release a patch/update for USB blaster classic/ver 1? They released it for Blaster II but not blaster I.

2. According to some forum posts here, Quartus Pro 21.1 fixed this issue (I assume both Blaster I and II). Can I just extract the driver folder for USB blaster I and use it for Quartus 20.1.1 Lite?

Thank you,
