I am trying to use the the  exec function to run a .exe   file. The .exe file runs , and finishes it's job. But it is not returning success code.
My code is like this...

$execfeedback =exec("startApplication.exe filename=aaa Id1=0 Id2=0 trace=true") or die ("I died while running Application!");
 startApplication.exe finished it's job successfully but it died by printing "I died while running Application".

I am using php 4.0.6 on w2k and IIS.
