Running the Design

Check the 'Program/Configure' box and set up the JTAG programming hardware connection via the 'Hardware Setup' button.

Okay, but which version? The 7.1 ?  Thx :)

I think the error-message indicate what version is built the project,

but yesterday I found another way ..

open the project (qpf) with Quartus (the version installed on your computer) and then

open SOPC Builder from the tools menu.

with the same settings push 'Generate' button to regenerate the project.

when generation compete push 'exit' button as the programme suggest.

now open the NIOSII and build the project and RUN.

perhaps to work with the new SOPC. it worked for me!!!
