How do I make .NET Framework 3.5 SP1 install quietly?

Question

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.

Answer 1

.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

Answer 2

The /q option is the correct one (/q, not \q):

dotnetfx35.exe /lang:ENU /q

This syntax is used in winetricks and it installs .NET correctly (see: load_dotnet35sp1()).

If it doesn't, make sure you've the right version of the dotnetfx35.exe file.

AutoHotKey

Alternatively you can use AutoHotKey to automate any installer wizzard.

Here is the example taken from winetricks:

SetTitleMatchMode, 2
run, dotnetfx35.exe /lang:ENU /q

Loop
{
    sleep 1000
    ifwinexist,, cannot be uninstalled
    {
        WinClose,, cannot be uninstalled
        continue
    }
    Process, exist, dotnetfx35.exe
    dotnet_pid = %ErrorLevel%
    if dotnet_pid = 0
    {
        break
    }
 }

Answer 3

Try calling the installer with these parameters:

dotnetfx35setup.exe /qb /norestart

Also, make sure all setup packages are not missing, you can use .NET Framework 3.5 SP1 full install package.
