Error returned (installing silent): If you try to install this applicaton on Windows 7 , error returned would be 7.

This application is not supportd on windows 7 . Link

So in order to get the same installed on windows 7 , you have to remove OS check that are placed in the following files :

• Adobe CS3\payloads\AdobeContribute4.1en_US\AdobeContribute4.1en_US.proxy.xml
• Adobe CS3\payloads\AdobeDreamweaver9en_US\AdobeDreamweaver9en_US.proxy.xml
• Adobe CS3\payloads\AdobeIllustrator13en_US\AdobeIllustrator13en_US.proxy.xml
• Adobe CS3\payloads\AdobePhotoshop10en_US\AdobePhotoshop10en_US.proxy.xml
• Adobe CS3\payloads\AdobeVersionCue3All\AdobeVersionCue3All.proxy.xml
• Adobe CS3\payloads\AdobeWebSuitePremiumen_US\AdobeWebSuitePremiumen_US.proxy.xml

Once this is done you can install this version on Windows 7 machine . 

What else i have changed :

1. Added files "Adobe CS3\payloads\AdobeWebSuitePremiumen_US\application.xml.override"

Content of this files were :

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

<Configuration> 

<Payload>

 <Data key="Serial" protected="0">XXXXXXXXXXXXX</Data>

 <Data key="Registration">Suppress</Data>

 <Data key="EULA">Suppress</Data>

 <Data key="Updates">Suppress</Data> 

</Payload> 

</Configuration>

Command line to install : setup.exe --mode=Silent --deploymentFile="install.xml" --codeSkipProcess=1

If codeSkipProcess is not added then you would be prompted to close microsoft applicaiton i.e. Oulook , word etc

Hope this helps .
