Generating Log File while Installing

[maverick786us]

I am installing an MSI file using this command


@echo off

set NeedReboot=No
set ErrorOccured=No

start /w msiexec.exe /I "D:\Maverick\Projects\Control Flash\Docs\Anomalies\Kornes\Krones_Megabundle_16_2008_04_21\ControlFLASH.msi"
/qb- ARPNOREMOVE=1 ARPSYSTEMCOMPONENT=1 ALLUSERS=1/L*v "C:\WinINSTALL2000\InstallLog.txt"
ADDLOCAL=All REBOOT=ReallySuppress

set return=%errorlevel%
if "%return%" == "0" (
echo Installation completed successfully!!
) else if "%return%" == "3010" (
echo A Reboot is necessary to complete the
installation!!
set NeedReboot=Yes
) else (
echo Error occurred during installation! Error
number is %return%
echo Error number: %return% > %tmp%\error.txt
set ErrorOccured=Yes
)


exit /b 0




Now I want to generate log file for this installation so i modified this command by adding this line


@echo off

set NeedReboot=No
set ErrorOccured=No

start /w msiexec.exe /I "D:\Maverick\Projects\Control Flash\Docs\Anomalies\Kornes\Krones_Megabundle_16_2008_04_21\ControlFLASH.msi"
/qb- ARPNOREMOVE=1 ARPSYSTEMCOMPONENT=1 ALLUSERS=1/L*v "C:\WinINSTALL2000\InstallLog.txt"
ADDLOCAL=All REBOOT=ReallySuppress /L*v "D:\Maverick\Projects\Control Flash\Docs\Anomalies\Kornes\Krones_Megabundle_16_2008_04_21\InstallLog.txt"

set return=%errorlevel%
if "%return%" == "0" (
echo Installation completed successfully!!
) else if "%return%" == "3010" (
echo A Reboot is necessary to complete the
installation!!
set NeedReboot=Yes
) else (
echo Error occurred during installation! Error
number is %return%
echo Error number: %return% > %tmp%\error.txt
set ErrorOccured=Yes
)


exit /b 0




But it generates an error saying qb to be an invalid command
