Cannot Install USB Drivers

Question

I cannot install the USB drivers that come with my Quartus installation. I have seen other users also with this issue: https://community.intel.com/t5/Intel-FPGA-Software-Installation/USB-blaster-won-t-install-certificate-outdated/td-p/1255595

It appears that the driver is not properly signed. I am attempting to use Quartus at my workplace where installing non-signed drivers is a violation of our information systems policy. I cannot disable this check to install the improperly designed drivers. Can this be fixed?

Hi,Seems like there is a need to reinstall the USB driver. Can you try by referring to the KDB below?https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/tools/2021/why-does-the-intel--fpga-download-cable-ii-driver-installation-f.htmlRegards,Bruce

Bruce,
That worked, thank you! I find it curious that Intel's user guide documentation does not mention this updated driver, nor has Quartus been updated to include it. However, I do appreciate your help.
