Quartus 5.0 ! It is a April 1st joke ;-) ? 



Hi, it seems your Quartus installation has been corrupted. 

You have Quartus 5.0 and Quartus 9.1SP2. 


You "SOPC_BUILDER...." environment may be corrupted : the "+" is suspicious, the paths should be separated by a ";" 


Try to redownload the Factory Flash through Nios II IDE.
