Why do I receive the following error when trying to generate my SOPC Builder system: "Generator program for module 'cpu' did NOT run successfully"?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description You may receive the above error if you have multiple versions of the Nios® II Embedded Design Suite (EDS) installed on the same machine.  When installing multiple versions of Nios II EDS, it is important to appropriately set the SOPC_KIT_NIOS2 environment variable when switching between versions of Nios II EDS.  Always ensure that SOPC_KIT_NIOS2 environment variable is set to the version of Nios II that corresponds with the version of the SOPC Builder that you are using.  For example if you launch SOPC Builder 6.0 ensure that the SOPC_KIT_NIOS2 environment variable points to the Nios II 6.0 installation directory.
