Hi,

The reason is that the driver signature has expired on USB-blaster. Please follow the step below to install the driver.

1. Select the “Start” button.
2. Type “startup”.
3. Select “Change advanced startup settings“.
4. Select “Restart now” under the “Advanced startup” area.
5. Select “Troubleshoot“.
6. Select “Advanced Options“.
7. Select “Startup Options“.
8. Select "Change settings".
9. Select “Restart“.
10. A menu will appear where you can press “7” on your keyboard to choose “Disable driver signing enforcement“.
11. When the PC restarts, use Device Manager to update the drivers. You may get a warning about the signature, but installation will go ahead.
12. Once finished, restart normally to re-enable signature enforcement.

Hi,

It is actually related to the USB-Blaster Driver Signature which has expired on January. This causes the driver installation to failed.
