USB Blaster on 64-bit Vista for Altera's Quartus

• If you can not program your boards using the USB Blaster, then you will need to configure Vista 64-bit to accept unsigned drivers as follows:
  • Select "Start | Programs | Acessories | " then Right mouse on "Command Prompt" and select "Run as administrator"
  • Select "Continue"
  • Type: bcdedit /set testsigning on
  • Type: bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS
  • Reboot your computer.
• Unfortunately, the four corners of your computer will now display Test Mode and the Windows version will appear in the top center of your display, e.g., Microsoft (R) Windows (R) (Build 6002: Service Pack 2).
