No luck installing StarOffice 8

Hi.

I'm quite new to this unattended stuff. I'm trying to get SO8 to install silently together with Windows using RunOnceEx. I've got the following file:

cmdow @ /HID
@echo off

SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx

REG ADD %KEY% /V TITLE /D "Installerar Applikationer" /f

REG ADD %KEY%\005 /VE /D "Acrobat Reader 7" /f
REG ADD %KEY%\005 /V 1 /D "%systemdrive%\install\AdbeRdr70_sve_full.exe /S /v/qn" /f

REG ADD %KEY%\015 /VE /D "Borttagning av skadlig programvara" /f
REG ADD %KEY%\015 /V 1 /D "%systemdrive%\install\Windows-KB890830-V1.8-SVE.exe /Q" /f

REG ADD %KEY%\025 /VE /D "Ad-Aware personal" /f
REG ADD %KEY%\025 /V 1 /D "%systemdrive%\install\aawsepersonal /S" /f

REG ADD %KEY%\035 /VE /D "StarOffice 8" /f
REG ADD %KEY%\035 /V 1 /D "%systemdrive%\install\StarOffice8\setup.exe /qn" /f

REG ADD %KEY%\055 /VE /D "Rensar upp och startar om" /f
REG ADD %KEY%\055 /V 1 /D "%systemdrive%\install\cleanup.cmd" /f

EXIT

This works nice for the other programs on the list, but SO installation seems to do nothing at all. I've tried installing it manually using the same parameters from the shell and it works without a problem. Anyone can see what I'm doing wrong here?
