Try launching the SBTGUI like this: a) Load your hardware design in Quartus II b) From Quartus II, launch SOPC Builder c) From SOPC Builder, launch the Nios II Software Build Tools GUI d) Try creating/building helloworld from there If that still doesn't work, here are some other more drastic things to try. 0) Quit all ACDS tools. 1) Make sure you don't have another install of cygwin on your computer that may be getting mixed up with the one Altera ships with ACDS. 2) Go into regedit and remove the HKEY_CURRENT_USER\Software\Cygnus Solutions key name, if there is one. 3) Look in your PATH environment variable and verify that there is no path entry with cygwin in it. If you see one, remove it. 4) Try the ACDS tools again. Altera ships two GUI environments in 9.1. Are you using the one called "Nios II Software Build Tools for eclipse"? or the one called "Nios II IDE"? The former is the one you should be using for all new projects. We refer to the older one as "The IDE". The newer one is sometimes shortened "SBT GUI" (for Software Build Tools GUI). -edj
