error to every NIOS II project

--- Quote Start ---

Problems:

there were two different problems.

The first was an incompatibility between NIOSII and VISTA.

when I worked in XP OS problem was that the project had been built in different SOPC Edition.

Solution:

i open the project with Quartus and regenerate SOPC with each version.

and then, the project version was compatible with Quartus-NIOS version.

Can you elaborate on what your solutions were please. I'm having the same exact problem. I believe I have possibly gotten around the VISTA issues, as I have been able to successully download and run 1 of the demos (Synthesizer). However, if I try any of the other ones, I can't get them to run. I get MAKE errors.

It looks the regenerate SOPC might be the solution, however, as I am new to Quartus, and have never used the SOPC before, I want to make sure I understand what to do. Did you simply open the project, then select SOPC from the Tools menu and hit Generate?

Did you make any changes in Quartus or SOPC Builder?

EDIT: I'm using Quartus 9.0 SP2 and NIOS 9.0 with the DE2-70 Development board.

Thanks in advance,
