Setup closed with exit code: 0x84C40013 - Silent Install error - SQL Server 2012 express management studio SP1

Question

I am trying to create a silent installation package for SQL Server 2012 Express Management Studio SP1. (both x86 & x64)
Prior to installation I have performed the following :
1. Turned ON the Windows feature 'Microsoft .NET Framework 3.5.1' (I had read somewhere on the internet that this is required prior to installation)
2. Installed Microsoft .NET Framework 4.0
I am using the following command line to perform an unattended install :
<EXENAME> /Q /IACCEPTSQLSERVERLICENSETERMS /ACTION=install /FEATURES=Tools 
However, the installation fails abruptly.
The application installs successfully with the following command line :
<EXENAME> /IACCEPTSQLSERVERLICENSETERMS /ACTION=install /FEATURES=Tools
The error occurs only while attempting to install the application with the /Q switch appended.
Please help.

Hello Fanny,
Thanks for providing the link to the SQL Server 2012 unattended install guide.
However, I must highlight that I was running the setup.exe with "Run As a Administrator" option and still facing the issue.
Anyways, I found out the root cause and I must say that it was a rather silly one.
As I had stated previously, the following command line was causing the issue :
<EXENAME>
/Q /IACCEPTSQLSERVERLICENSETERMS /ACTION=install /FEATURES=Tools
I simply changed it to the following and it worked....
<EXENAME>
/QUIET /IACCEPTSQLSERVERLICENSETERMS /ACTION=INSTALL /FEATURES=TOOLS
It so seems that everything must be in CAPITALS for this to work.
