DE2-70 : Nios II EDS cannot build "Ethernet Packet Sending/Receiving" of Altera demo

Hi all,

I am working on Ethernet port of DE2-70. Now I want to see the Ethernet demo of Altera. I did as followings:

+ Download the latest demonstrations from http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=53&no=226&partno=4

+ Download and install Quartus 10.0 , Nios 10.0 from ftp://ftp.altera.com/outgoing/release/

Then, Quartus 10 can compile and download the HDL code to FPGA. But, NIOS II EDS 10.0 cannot build the software (DE2_70_NET\Software). I push "build project" then nothing happens!!!.

Then, I also try with a 32-bit machine ( the current machine is 64 bit), but it still doesn't work. I don't know what to do ???

Does anyone successfully build the Ethernet demo of DE2-70???

PS: Previously, I tried to run the mouse demonstration on accompanied CD with Quatus and Nios 11.0 but the same problem happened (NIOS II EDS cannot build the software )

Thank you all!
