Hi,

I had this problem when i tried to use QuartusII 4.2 with the previous NiosII version (v1.0 sp1). It is caused by a version conflict between the Perl generator scripts. When you do an Altera product upgrade, make sure you completely remove the old version first.

If you have Nios II v1.01 or older installed, before you upgrade to Nios II v1.1 uninstall the old Nios II kit and then go to /altera/kits (if you kept the default install directory) and manually delete the nios2 folder. If you didn't do this, uninstall Nios II v1.1 completely, manually remove the aforementioned folder then reinstall.

If this doesn't fix your problem, do the uninstall/manual remove thing on the quartus folders as well, then reinstall.

Good Luck
