problem to download ELF file to DE-1 board

I'm trying to download an elf file to the DE-1 board as described in the book:
"EMBEDDED SOPC DESIGN WITH NIOS II PROCESSOR AND VHDL EXAMPLES" from Pong P. Chu,
page 203:
"Load the .elf file to the designated memory modules,
Select the application directory, ledl.test, in the Navigator subwindow. Right-click the mouse and select Run As >- Nios II Hardware"

I have build that example project, but at right clicking on the project I get only the choice: Run-As -> Local C/C++ Application,
the sof file I already downloaded before

I'm using the Eclipse EDS version:
91sp2_nios2eds_windows

Thx,
Adriano
