Windows – How to make .NET Framework 3.5 SP1 install quietly

.net framework64-bitinstallationinstallerwindows 8.1

I am trying to install, as part of my chained bootstrapper installation project, .NET Framework 3.5 SP1. But, when you run the installer, even by itself, with /q /norestart, it is anything but quiet. I would expect no user interface, yet I get presented with the following:

Is there any way to actually make it quiet? I've looked at other threads on Stack and elsewhere, and they all seem to imply that this would be the way to make the installation take place quietly, yet it doesn't.

Note: I know, in the command prompt screenshot I used \, but even with /, same thing.

Note: I've tried both the full and not-full versions of the .NET Framework 3.5 SP1 redistributable; same thing.

.Net 3.5 is already part of Windows 8, so the installer doesn't work. You can use DISM to install .Net 3.5:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs
