Start installation and wait at the first Window

go to %tmp% copy these files

bdfree.msi

Setup.Exe

InstMsiA.Exe

InstMsiW.Exe

to your installation folder

then cancel installation

syntax is

setup /qb or

setup /qn

I believe that the InstMsiA.Exe & InstMsiW.Exe files are unneeded - I think they are for updating the windows installer. With XP - they should be up to date already.

Not 100% sure - but it might be something you can check out.

this would save you some space on the cd.

Did a quick google -

To download the Windows Installer file from the Web, visit one of the 
following Microsoft Web sites:

Instmsia.exe for Windows 98 or Windows Millennium Edition:
http://download.microsoft.com/download/WindowsInstaller/Install/2.0/W9XMe/EN-US/InstMsiA.exe

-or-

Instmsiw.exe for Windows NT, Windows 2000 or Windows XP:
http://download.microsoft.com/download/WindowsInstaller/Install/2.0/NT45/EN-US/InstMsiW.exe

you are right, just remove those files

have a nice day !

Cheers
