Hello, I have installed the Quartus-II 8.0 SP1 on HP dv4-1020us notebook (64bit Windows Vista), the software is runing fine. When I plug in the usb blaster cable which connects to a Terasic DE3 board, the computer successfully found the device and serached for the driver. I pointed the driver location to "Altera\80\quartus\drivers\usb-blaster" and it failed being installed. Wondering if this is related to Vista 64bit since I can install the driver onto a 32bit Vista without any problem. Any one has an input on this problem? Thanks!

USB-driver is supported for 64-bit Windows Vista too: http://www.altera.com/support/software/drivers/dri-index.html Did you specify the 64-bit driver under the drivers\usb-blaster\ directory?

Thanks for the reply! Yes, I tried many times by browsing different directories. If I specified the directory \x64, then it showed the error message "Windows could not find dirver software for your device". If I pointed to the directory above (i.e., \usb-blaster), then it displayed the message saying "Windows found driver software for your device but encountered an error while attempting to install it". But it didn't indicate what type of error is. At one time, I noticed the Windows says "the driver's digital signature is not certified and this version of Windows requires the certified signature to install the dirver". Wondering if this is the cause for the problem.

I looked at the file "usbblstr.inf" under the driver directory "usb-blaster" and found that the 64 bit driver files are all tied to the name "amd64" or "NTamd64", but my notebook's cpu is intel's Core 2 Duo. Don't know if this is the reason the Windows couldn't load the 64bit driver files.

Altera recommends "Install Anyway" when you encounter this warning.

Core 2 Duo is 64-bit processor and the corresponding driver should be in the directory named x64. Is there any other software installed on your system which is using USB-blaster drivers.

richo25, I'm not sure what you mean by "test mode." If you're refering to the boot switch to turn off driver signing, that is not an option in some circumstances. In fact, the only time this really even makes sense is when you are using your machine as a driver test bed.

please try the driver included with 9.1 for Windows Vista, it should be resigned.

Yes, thepancake, this issue has been resolved in 9.1. Probably this thread should be closed, if that's possible on the board.

Just try this, it might work because I also encountered the same problem. I searched the solution throughout the forum but I still couldn't find it. Then I just tried to set to upper directory: C: .../quartus/drivers. Then, I ticked the subfolder inclusion. And it works..

Hope my post can help you...
