Hi, I have just purchased this DE0-nano board.
PC I am using is 64 bit Windows 7 I am doing what you have explained to do Device manager -> then pointing it to the quartus directory with USB Blaster Driver but it says windows cannot update the driver so I cannot connect with the board. Any other suggestions as to what I am doing wrong? I have gotten this PCB to work on an old 32 bit desktop. Thanks Nig - Altera_Forum

Try 12.1, the driver works properly.

Hi Leon
Thanks for your reply, I have tried this now, removing previous version and updating to 12.1, Unfortunately this doesn't work either, I'm pointing them to the new folder with the drivers but getting the same 'windows could not find the driver' This is pathetic that this is such a problem, judging by the amount of threads i've read, that they can't get this right. - Altera_Forum

I'm using the same, unfortunately I have, what a pile of crap having to jump through hoops to get an out of the box unit to connect with a pc even before I start trying to work with the thing,
Just tried the standalone programmer there & still nothing, any other suggestions greatly appreciated, As I said I plugged this into a 32 bit machine in college & connected straight away. - Altera_Forum

It might be trying to install the wrong driver. Mine is using these files:
usbblstr.sys usbblstr64.dll usbblstrlang.dll usbblstrui.dll usbblstr32.dll If it is the wrong one you might need to install it manually. - Altera_Forum

I encountered similar issue before. Go to Device Manager, try manually add it to this path to the USB device:
C:\altera\12.1\quartus\drivers\usb-blaster-ii\ (not the one layer below e.g. x32 or x64). The system will pick up from .inf and the correct x86 driver from there.
