Experiencing Problem Running SQLCMD

[ggrewe]

I have a Basic MSI (IS2009). There is an Installscript Custom Action that will attach a database to SQL Express 2005 and add some users. I am having two problems;

1. The CA runs, but the SQL Script is not executed successfully. The command window opens and closes way to fast to read anything. I can run the identical code from a CMD prompt and it completes successfully.

2. The Status window does not close after the CA runs. I have to kill it through task manager.

Notes:
The Custom Action is set for Immediate Execution, the sequence is after InstallFinalize.

InstallScript:


export prototype AttachDB(HWND);

function AttachDB(hMSI)

STRING szMsg, szProgram, szCmdLine;
NUMBER nReturn;

begin


szProgram = "SQLCMD.EXE";
szCmdLine = "-S localhost\sqlexpress -d master -E -i c:\temp\data\AttachEXDB.sql -o c:\temp\data\AttachEXDB.log";
szMsg = "Attaching database named c:\temp\data\local_820_ng on LOCALHOST\SQLEXPRESS. Please wait...";

nReturn = SdShowMsg(szMsg, TRUE);

// nReturn = LaunchAppAndWait(szProgram, szCmdLine, LAAW_OPTION_WAIT | LAAW_OPTION_MINIMIZED | LAAW_OPTION_SHOW_HOURGLASS);
nReturn = LaunchAppAndWait(szProgram, szCmdLine, LAAW_OPTION_NOWAIT );

if (nReturn < 0) then
SdShowMsg(szMsg,FALSE);
SprintfBox (SEVERE, "Aborting Installation","Error in running &#37;s %s", szProgram, szCmdLine);
abort;
endif;

end;


SQL Script:


USE [master]
GO
CREATE DATABASE [LOCAL_820_NG] ON
( FILENAME = N'C:\Temp\data\LOCAL_820_NG.mdf' )
FOR ATTACH
GO
if exists (select name from master.sys.databases sd where name = N'LOCAL_820_NG' and SUSER_SNAME(sd.owner_sid) = SUSER_SNAME() ) EXEC [LOCAL_820_NG].dbo.sp_changedbowner @loginame=N'sa', @map=false
GO

CREATE LOGIN LOCAL_820_NG WITH PASSWORD = '820_NG', DEFAULT_DATABASE = LOCAL_820_NG
GO

use [LOCAL_820_NG]
GO

CREATE USER LOCAL_820_NG FOR LOGIN lOCAL_820_NG
GO

sp_addrolemember @rolename = 'db_Owner' , @membername = 'LOCAL_820_NG'
