Hi fabmal004, did you ever find the cause of this issue?  

 It turns out that I have just picked up a project made in 7.2sp3 and I have got the same error message.  So far I have tried re-installing Quartus, Nios II and the IP megacore incrementally from v7.2 sp1 through to sp3. I have also had a look through the installed sopc folders and I can see that the nios cpu component files definately exist in my install, but for some reason Nios is not finding them.  Anyone else have any ideas or a solution??

While you are at it you can also delete the .sopc_builder folder as well as the sopc builder will re-generate that file when you run it again.  Rebuild the IP in sopc builder, rebuild the hardware in Quartus.   Launch Nios II and do a clean and a build.  I hope this may help anyone who is stuck with the same compiler error.
