This is how I do...
1 download Nero installer
2 download
foood icons
3 extract the Nero installer with winrar
4 now add all the extracted Nero files to winrar again and put these comments:
CODE
Setup=Setupx.exe /NOCANCEL /NOLICENCE /NOREBOOT /NO_UI /SILENT /SN=xxxx-xxxx-xxxx-xxxx-xxxx-xxxx /WRITE_SN
TempMode
Silent=1
Overwrite=1
Title=Nero 6.6.0.13 Ahead Software AG
5 convert your archive into SFX and choose advanced sfx options > tab: text & icons > load sfx icon from the file...choose the icon you like (the one u dl-ed from foood.net)
and hit the OK button
