AIR NativeProcess on Mac gives Error:3219, all solutions failing

hi guys,

I've read up most solutions for this error and none seem to apply.

I'm running a basic AS3 app in FlashBuilder, on OS-X.

• descriptor is set to extendedDesktop
• have set the profile in FB to 'extendedDesktop'
• am publishing as 'signed native installer'
• I've tried launching the file from both:
• app:/demo.sh
• file:///Users/visualife/Desktop/AE/demo.sh
• the target file is set to 777 (executable)
• the target file runs fine when directly targetted
• i'm running the exe on the same OS and machine it's created on
• changing the 'demo.sh' file to a jpg etc doesn't change anything

No matter what I try I get told native process is support, everything runs fine until start is called then a Error: 3219 is thrown with no further information.

all help greatly appreciated!

I've included my code below:
