In any event, running Programmer now worked, though I think I had to go to Hardware Setup and choose the USB Blaster from the menu to make it appear. I think I retried the driver installer again manually with the same results.

With 18.1, the Altera driver install popup had 4 drivers, 2 of which installed (including the `Altera Altera USB-Blaster.' one), and 2 failed. I finally went back to the Intel site and tried version 18.1 (the version mentioned in SwRI's guide). No reason was given nor found for the failure. Upgrading drivers via Windows Device Manager also failed. I then tried installing the driver manually as the popup had suggested (qprogrammer\drivers\DPInst.exe), but it still failed. Programmer then failed to find the USB Blaster (not entirely unexpected given the driver install failure), despite it being visible in Windows Device Manager.

When installing Quartus Prime Programmer Lite version 20.1.1.720 (the latest version, offered by default), the Altera USB Blaster driver failed to install, with a red X next to `Altera (WinUSB) JTAG c.' in a popup (the sole driver listed).As others have noticed, it doesn't require detailed electronics knowledge, but prior experience successfully dis- and re-assembling devices with small connectors, ribbon cables etc.

Finally attempted the QHY174 firmware upgrade (successfully) and thought I'd share my experience.
