LaunchAppAndWait() doesn't Work With Window 7.
Hi,
I have migrated project to IS 2011.
We are using LaunchAppAndWait (szCmdLine, "", bWait) function to launch EXE.
Here szCmdLine is "C:\Documents and Settings\Rahul\Desktop\redist\dotnetfx2.0.exe"/q:a /c:"install.exe/qb"
Does any body know why this function is not working with Window 7?
It works with Window XP.

Are you trying to place this code in a custom action?
if yes, then try to set the in-script execution to deferred in system context.
this should elevate the process on Win 7.

Thanks for the reply,
I have written this function in Setup.rul script file which IS calls.
This is not the custom action.
Do you have any info about LAAW_OPTION_USE_SHELLEXECUTE parameter?
I think by using that Parameter Install shield script engin will call ShellExecuteEx funciton. And that will support window 7.

Yeah, in this case you can use LAAW_OPTION_USE_SHELLEXECUTE
in LaunchApplication instead and have the LAAW_SHELLEXECUTEVERB = "runas".
This should elevate your process on Win 7.

Hi Thanks again,
I was trying below function but it is not working as expected,
LaunchApplication(szCmdLine,"","",1000, LAAW_OPTION_WAIT | LAAW_OPTION_USE_SHELLEXECUTE)
Do you have any working code for this function LaunchApplication()?

Hello Roman,
below is the piece of code i use to elevate an install on Vista/Win 7 etc
*************************************
function OnBegin()
STRING szProgram,szCmdLine,szDirectory;
NUMBER nShowWindow,nTimeOut,nOptions;
begin
szProgram = SUPPORTDIR ^ "setup.exe";
szCmdLine = "" ;
szDirectory = "";
nShowWindow = SW_NORMAL;
nTimeOut = 10000;
nOptions = LAAW_OPTION_USE_SHELLEXECUTE ;
//This ensures that the application is always run with full administrator privileges
LAAW_SHELLEXECUTEVERB = "runas";
//A message box just for internal testing
MessageBox("Click ok to Launch",INFORMATION);
// launch application--setup.exe in this case
LaunchApplication(szProgram,szCmdLine,szDirectory,nShowWindow,nTimeOut,nOptions );
end;
*****************************

Hello rrinblue22,
thanks for the code.
Does the
"function OnBegin()"
wait until the extern setup ends?

Hey Roman,
If you want OnBegin() to wait then you may need to consider using the
nOptions = LAAW_OPTION_WAIT|LAAW_OPTION_USE_SHELLEXECUTE ;
in the sample script.
this would wait for the external application to complete/abort.
