title: Execute command line statement in installshield / installscript
body: <p>How do I execute the following command in installscript during installation?</p>
  
  <pre><code>netsh.exe advfirewall firewall show rule name="PowerSI (Release ASI 16.64)" || NETSH.EXE advfirewall firewall add rule name="PowerSI (Release ASI 16.64)" dir=in action=allow program="d:\Cadence\HIM_asi1664\ASI\Update4\SpeedXP\SpeedXP Suite x64\PowerSI.exe" enable=yes profile=any description="d:\Cadence\HIM_asi1664\ASI\Update4\SpeedXP\SpeedXP Suite x64\PowerSI.exe"
  </code></pre>
  
  <p>Note that the above command contains the executable name i.e. <code>netsh.exe</code> twice and this is where the problem is. I tried <code>LaunchAppAndWait</code> first by using the whole command as the name of executable and passing an empty string as argument. Next I tried was passing the first netsh.exe as program name and the remaining text as argument. Both the approaches did not work.</p>
