Hi Mike,

If you are sure your Quartus version is a final release, not a beta (this 4.2sp1 must be very new, I'm still in process updating to the original v4.2 release) then probably it's a component version conflict problem. Try removing all Altera software (including manually deleting the folders left after uninstall) then install again. Probably it's also worth asking Altera if this new Quartus version is compatible with the Nios release you have, or you need to wait for a new NiosII version as well.

Regards,

C
