Hey people, After succesfully creating my first unattended XP installation, i decided to add some applications and windows components. I am using RunOnceEx, my file looks like this: @echo off SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx REG ADD %KEY% /V TITLE /D "Windows componenten en programma's installeren" /f REG ADD %KEY%\001 /VE /D ".NET Framework 1.1 + SP1" /f REG ADD %KEY%\001 /V 1 /D "%systemdrive%\Install\Microsoft\NETframework11+SP1\netfx.exe" /f REG ADD %KEY%\002 /VE /D ".NET Framework 2.0" /f REG ADD %KEY%\002 /V 1 /D "%systemdrive%\Install\Microsoft\NETframework20\dotNET20_silent.exe" /f REG ADD %KEY%\003 /VE /D "Visual J# Runtime files update" /f REG ADD %KEY%\003 /V 1 /D "%systemdrive%\Install\Microsoft\VisualJ#RedistributablePackagedotNET20\install.exe /Q" /f REG ADD %KEY%\005 /VE /D "Acrobat Reader 6" /f REG ADD %KEY%\005 /V 1 /D "%systemdrive%\install\AcrobatReader\AR6.exe -p\"-s /v\"/qn \"\"" /f REG ADD %KEY%\006 /VE /D "Java 2 Runtime environment V5.0 Update 6" /f REG ADD %KEY%\006 /V 1 /D "%systemdrive%\install\JavaRuntime\Java50.msi /passive" /f REG ADD %KEY%\075 /VE /D "WinRAR 3.20" /f REG ADD %KEY%\075 /V 1 /D "%systemdrive%\install\winrar\WinRAR320.exe /s" /f REG ADD %KEY%\076 /VE /D "Nero 6.3.1.17" /f REG ADD %KEY%\076 /V 1 /D "%systemdrive%\install\Nero\Nero63117.exe /SILENT /NOREBOOT /SN=XXXX-XXXX-XXXX-XXXX-XXXX-XXXX /WRITE_SN" /f REG ADD %KEY%\077 /VE /D "Daemon tools 3.4.7" /f REG ADD %KEY%\077 /V 1 /D "%systemdrive%\install\Daemon\Daemon347.msi /passive" /f REG ADD %KEY%\079 /VE /D "Office 2003 Proffesional + SP2" /f REG ADD %KEY%\079 /V 1 /D "%systemdrive%\install\Microsoft\OfficeProff2003+SP2\setup.exe TRANSFORMS=Unattended.MST /qb-" /f REG ADD %KEY%\155 /VE /D "Opruimen en opnieuw opstarten" /f REG ADD %KEY%\155 /V 1 /D "%systemdrive%\install\cleanup.cmd" /f EXIT As you can see, i have .NET 1.1 + SP1 (Slipstreamed) .NET 2.0 j# runtime Acrobat reader Winrar Nero Deamon tools Office 2K3 The problem is, when i test this unattended installation, everything is installed execpt office 2K3. The installer runs, but stops without returning a message, and office isn;t installed. I tested the office installation only by removing all other program entry's from RunOnxeEx and voila, office installed correctly. I suspect that the .NET frameworks cause some files to be locked beacause it requires a reboot, and thus office 2K3 cannot acces these file while installing. Is there anyone who can confirm this? Or have had similar problems?
