lol, sorry, looks like im answering my own questions again: REG ADD %KEY%\050 /VE /D "Microsoft Office 2003 Professional" /f REG ADD %KEY%\050 /V 1 /D "%systemdrive%\Install\Office2003\setup.exe TRANSFORMS=Unattended.mst /qb-" /f so i should try the runonce method using above script and presumably copy most and edit for the next app? eg: REG ADD %KEY%\005 /VE /D "7 Zip 4.18" /f REG ADD %KEY%\005 /V 1 /D "%systemdrive%\Install\7Zip\7zip.exe -y /S" /f think I will shut up now and stop asking questions hehe
