Honored ContributorOk after more then 10 times of reinstall, reboot, program flash memory... finally found the problem.
I'm using windows10 which enforce driver signature verification, so I disable it by entering the test mode. But that's not enough, for some reason it only allowed you to install kernel driver module but not the board driver. I have to use the Advanced Boot Option to disable driver signature verification, then when installing board driver it will ask you twice if you want to install non-signature driver. Technically not Altera's problem, and they did tell you to disable driver signature verification on this page (https://www.altera.com/support/support-resources/knowledge-base/solutions/fb321729.html), but the message return 0 error and install successfully is quite misleading..
