USB-blaster won't install, certificate outdated

[123jan456]

Dear community and Intel employees,

I just bought a new laptop and had to reïnstall Windows and Quartus. But the USB-blaster drivers just wouldn't install. After a whole day of trying to figure out the problem I noticed that the certificates for the USB-blaster drivers had expired last month (Januari-2021).

If USB-blaster just won't install and you are installing the drivers for the first time on a Windows system after 1-2021 you probably have this problem.

The solution:

1) Follow these "instructions" to start Windows in a way that it doesn't require drivers to have valid signatures.

2) Restart the driver installation program located at: "C:\intelFPGA_lite\<version>\quartus\drivers\DPInst.exe"

3) When asked, allow Windows to install drivers that have an invalid signature.

4) Use device-manager to reïnstall the driver for your USB-blaster device. You can let Windows look for the correct driver by itself of select the folder "C:\intelFPGA_lite\<version>\quartus\drivers\"

If it still doesn't work try rebooting with your device disconnected.

I posted this message to prevent other people from wasting their time and in the hope that Intel will renew the certificates.

Cheers,

Jan

Hi Wani,

Are the certificates now fixed for new installs? I have recently installed multiple new versions of Quartus and the certificates are outdated.

Thank you,

Travis

Hi Travis,

Note the solution I put in my message if you can't wait.

Do you or does anyone know if Intel plans to release the drivers with updated certs anytime soon for the Quartus-Lite version?  The solution to disable security from Windows OS does not meet our University's security initiatives whether for our student lab workstations or faculty devices.  This is almost a year now and no mention of driver cert updates for Quartus-Lite.
