Deferred execution in system context

[dracan]

Hi. I've got a custom action that runs one of my IS script functions. This works fine if it's set to immediate or deferred. However, if I set it to "deferred execution in system context", then it never gets run.

Any ideas what's causing this?
Cheers,
Dan.

Odd, this seems to working today! Can't think of anything related that I've changed.

Now we're having our QA department saying that the tasks I've changed to "deferred in system context" aren't happening 😞

Are there some scenarios where deferred in system context wouldn't run, when immediate execution would run?

Cheers,
Dan.

What do your scripts do. Remember in system context you don't have access to a profile. Maybe your scripts need that? Ask QA for a verbose log too and that should tell you if it attempted to run your scripts or not. Unfortunately without a log you don't have much to go on right now

Below is one of my functions. Note that the SprintfMsiLog logs aren't even appearing. Also below that are the relevant bits of my logs - the CA seems to be being called, but not the Installscript.

function AddToGamesExplorer(hMSI)
STRING szErrorString;
STRING szCustomDataDirecory;
NUMBER nLength;
begin
	SprintfMsiLog("Start:AddToGamesExplorer");

	nLength = MAX_PATH + 1; 
	MsiGetProperty(hMSI, "CustomActionData", szCustomDataDirecory, nLength);
	StrRemoveLastSlash(szCustomDataDirecory);

	if(LaunchApplication(szCustomDataDirecory ^ "Misc\\GDFInstall.exe", "/allusers /installpath \"" + szCustomDataDirecory + "\" main.exe", "", LAAW_STARTUPINFO.wShowWindow, LAAW_PARAMETERS.nTimeOut, LAAW_OPTION_CHANGEDIRECTORY | LAAW_OPTION_FIXUP_PROGRAM | LAAW_OPTION_USE_SHELLEXECUTE | LAAW_OPTION_WAIT) < 0) then
		NumToStr(szErrorString, LAAW_PARAMETERS.nLaunchResult);
		MessageBox("Failed to run " + szCustomDataDirecory ^ "Misc\\GDFInstall.exe (all users)(" + szErrorString + ")", WARNING);
	endif;

	SprintfMsiLog("End:AddToGamesExplorer");
end;

Well according to the log the CA was definitely fired so the problem must be within the script itself. Do QA see the messagebox? Also you are only checking for negative return error codes. I suggest you check for <> 0 then the messagebox might provide some more info. I would also suggest you remove that messagebox once you have this issue sorted otherwise your installation can't be remotely deployed silently. Instead it should be logging.

Turns out it was a bug in Installshield. I used the hotfixed mentioned in this thread and it fixed the problem 🙂
