What exact error do you see?  "I have a problem" isn't helpful
at all.

What are these \" ?  Don't you mean \\ ?
Why are you running cmd to call the application?  Why not call it
directly:

  system ("/cygdrive/c/users/mmurdoch/ACE/sixs \
           < /cygdrive/c/users/mmurdoch/ACE/sixSIn.txt \
	   > /cygdrive/c/users/mmurdoch/ACE/sixSOut.txt")

?

Or write a shell script and call that?
