12 years agoYou could start by checking the SOPC_BUILDER_PATH environment variable. You probably have an installation problem and reinstalling both Quartus and Nios II should fix it. By the way are your version numbers correct? I'm not sure that the IDE 7.0 can work with Quartus II 9.1. You'd better use the same version for Quartus and the Nios II IDE. Besides I don't think that Windows 7 is officially supported by Quartus II 9.1, you may have to download and install a more recent version.
