Help needed in updating the available hardware section of quartus 2 to USB blaster

Hello,

I am new to the FPGA environment and just started with FPGA design. As the preliminary design step, I installed quartus 2 software and the USB blaster driver that is needed for programming the Altera Cyclone 3 EP3C25 FPGA. I am however not able to update the available devices section in quartus 2 to USB Blaster. It still shows Ethernet Blaster and the Add New Hardware tab also shows the same. Can someone please help me. I am stuck and not able to load the .sof file as a consequence of this.

Regards,

Ranjan
