hi,

i have installed quartus II 13.0 programmer on my laptop.

i used USB blaster, and tried to program Cyclon E.

if i used the computer in my work, the programming successful. if i connect the usb blaster to my laptop, it isnt working.

the driver of usb blaser is installed in the Device Manager.

i used win10 in the laptop.

in my work is win7.

i downt know what wrong. i also tried to install quartus 17.1 lite, but the error still exist.

Your problem is probably related to the OS (Win 10 on the laptop). It could be because of "Driver Signature Enforcement" or some driver incompatibility with Win 10. Take a look at the two following links and see if they can help you find a solution:

Hi,

Can you try to re-install the USB Blaster driver from the drivers folder Intel Quartus Prime Standard edition v17.0/17.1 or Stand-alone Quartus Prime Programmer v17.0/17.1? You can refer to the following KDB link:

You should be able to download the Stand-alone Quartus Prime Programmer from the following link:
