What are the system requirements for MCR2013b installation ?

Hello,

I am writing a documentation for a program which needs the installation of the MCR2013b and I am now looking for the system requirements for the MCR installation. The only information I can find is in the file readme.txt included in the installation package where it is written:

2. System Requirements -------------------

   For information about the system requirements for this 
   release, see the installation guide for your system. A copy
   in PDF format is available in the top-level directory 
   of the installation disk. 

   For the most up-to-date system requirements information,
   go to the Support page on the MathWorks Web site, www.mathworks.com.

But I cannot find any pdf mentionning the minimum requirements nor any information on the website. Can anyone help me with that ? Thanks, R
