Contribute CS3 Silent Install Failed

I'm trying to install Contribute CS silently on several computers, however all of the components install except for Contribute. I followed the steps in the Enterprise Deployment Options technical paper.

First I created the application.xml.override file with the following entries:
<?xml version="1.0" encoding="utf-8"?>
<Configuration>
<Payload>
<Data key="Serial" protected="0">11XXXXX9XXXXX3XXXXXXX81X</Data>
<Data key="Registration">Suppress</Data>
<Data key="EULA">Suppress</Data>
<Data key="Updates">Suppress</Data>
</Payload>
</Configuration>

Next, I copied it to the payloads\AdobeContribute4.1en_US directory.

I'm running <Path to setup.exe> --mode=Silent -–deploymentFile =
<Path_to_deployment.xml> from a command line. I continue to get Error code 6: Silent workflow completed with errors.

My deployment file has the following entries:
<?xml version="1.0" encoding="UTF-8" ?>
- <Deployment>
- <Properties>
<Property name="installLanguage">en_US</Property>
</Properties>
- <Payloads>
- <!-- Adobe Contribute CS3
-->
- <Payload adobeCode="{11439DFB-0658-42C7-926D-B66985857733}">
<Action>install</Action>
</Payload>
</Payloads>
</Deployment>

When I look at the log file, all I see is
ERROR
The following payload errors were found during install:
- Adobe Contribute CS3: Install failed
[ 2572] Thu Jun 21 11:04:10 2007 INFO
-----------------------------------------------------------------
------------------ END Silent Installer Session

I made sure the PC has local admin rights. I also made sure no other application was running in the background. What am I missing?

I've been working on this for several days now. Any help would be greatly appreciate!
