Getting windows 10 to install the usb blaster driver

Hi all-

I can’t seem to get the usb-blaster driver to install. When the cable is attached to the DE10-standard board, windows automatically installs a driver for USB Serial Port (COM4) instead of showing “unknown device”. Charging ahead anyway, I try to update with the quartus usb-blaster driver, but windows comes back and reports that the best drivers are already installed.

There was a post at Terasic/Altera that suggested disabling the driver signature enforcement and as far as I can tell I’ve got that done. Still no success.

Has anyone had a similar problem and been able to solve it?
