Management Studio 2008 Express Install issue

I have some trouble installing Management Studio 2008 Express through C#-Code. 
The code looks like this:
using (Process MMSInstall = new Process())
{
    var psi = new ProcessStartInfo(PathExe. FullName, "/qs /Features=SSMS /Action=Install");
    MMSInstall. StartInfo = psi;
    MMSInstall. Start();
    MMSInstall. WaitForExit();
}

PathExe is a FileInfo-Instance. 
But the installation always fails:
Exception type: Microsoft. SqlServer. Setup. Chainer. Workflow. NoopWorkflowException
    Message: 
        No features were installed during the setup execution.  The requested features may already be installed.  Please review the summary.txt log for further details. 

When installing via command prompt
C:\>SQLMANAGEMENTSTUDIO_X86_DEU.EXE /qs /Features=SSMS /Action=Install

everything works fine. 
I looked through the logfiles (Detail.txt), and spottet a difference:
When running from the command prompt, 'Setting: MEDIALAYOUT' is set to 'Advanced' (pastebin.org/36222), when installing from my little C#-App it's set to 'Core' (pastebin.org/36221)
I tried to append /MEDIALAYOUT=Advanced to the ProcessStartInfo-Arguments in my code, but this options is ignored.  I don't know what this parameter does, and I could not find any documentation about it. 
Any ideas how to solve this or where to look for? 
I am testing on Windows Vista Ultimate SP1

A:

instead of calling the executable directly call %windir%\system32\cmd.exe 
Cmd has a /C switch which allows you to pass in a command to run.   So you'd pass in '/c "SQLMANAGEMENTSTUDIO_X86_DEU.EXE /qs /Features=SSMS /Action=Install"' 
as a parameter.
