hi,

Currently, there's no way to change this in the setup and deployment project. But you can try to change the package.xml which is located in "System Drive:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\DotNetFX3 5SP1\en"

The following is part of that file:

<!-- Defines how to invoke the setup for .NET Framework redist -->
<Commands Reboot="Defer">
<Command PackageFile="dotNetFx35setup.exe"
Arguments=' /lang:enu /passive /norestart'
EstimatedInstalledBytes="30000000"
EstimatedTempBytes="30000000">

You do need to know each element represents, and change them carefully. So you'd better back up them in case broken the file.
