detecting exit code

[Darain]

I was trying to detect errors with some customized programs called in the InstallScript of my INstallScriptMSI project. In my "testError.exe" program, I flagged the exitcode to 1 or 0 respectively when encountered errors.

I use the following IS function:
nResult = LaunchAppAndWait(SUPPORTDIR ^ "testError.exe", "", WAIT);
But I soon found out that this function always return 0 no matter what was returned by testError.exe. And apparently all [FONT="Courier New"]LaunchApp() [/FONT]related functions would do the same.

So, is there a way to retrieve the exit value of testError.exe with a InstallScript function, or any other way?

The return value of LaunchAppAndWait (or LaunchApplication) indicates only that the application was launched successfully.

To retrieve the return value of the launched application evaluate:
LAAW_PARAMETERS.nLaunchResult
(if LAAW_OPTION_WAIT option was specified)

That worked out just fine.
Thanks!
