[Qucs-help] ASCO optimizer

[<Geo...@ao...>]

To whom it may concern,
 
I have been unable to optimize circuits in QUCS. I am running on windows  XP. 
I have read where others have solved this problem by adding the qucs/bin  
directory to the PATH environment variable. I am not real computer literate and  
do not know what this means and how to fix the problem. Can you send more  
detail? Following is the QUCS message I receive:
 
Thanks Bill Johnson
