Error 0 when installing indesign CS5 in silent mode using a command line.

Hello I am trying to install Indesign CS5 in silent mode using commande line: Set-up.exe --mode=silent --deploymentfile="C:\Temp\Adobe Indesign CS5\InDesign_7_5_LS4\Adobe InDesign CS5.5\deploy\install.xml" --action=install

I modified install.xml include product code and licence number:

<?xml version="1.0" encoding="UTF-8" ?>

<Deployment>

  <Properties>

     <Property name="INSTALLDIR">C:\Program Files (x86)\Adobe</Property>

     <Property name="installLanguage">fr_FR</Property>

     <Property name="serialNumber">XXXXXXXXXXXXXXXXXXXXXX</Property>

  </Properties>

  <Payloads>

    <!-- AdobeInDesign7xAppBase-mul -->

    <Payload adobeCode="{857CC5F0-040E-1016-A173-D55ADD80C260}">

      <Action>install</Action>

    </Payload>

  </Payloads>

</Deployment>

.

The installation ends with code : 0 (installation successful) but nothing is installed.

Can you help me on this issue?

Regards
