Command Line Installation

Has anyone tried to do the command line installation per the
instructions in Chapter 19 of the CRM Implementation guide?
Specifically, I am trying to configure a command line installation for
the Outlook Client but try as I may, I just cannot get the msiexec
utility to execute the procedure. This is what I've done (which is
according to the instructions in the guide):

1. Copy outlook installation CD to network folder and shared it
2. Run: msiexec client.msi /A /L "outlookClient.log" /config
"outlook.xml" (in the directory where the outlook.xml exist)
3. The outlook.xml looks as follows:
<CRMSetup>
<Client>
<WebsiteUrl>http://crm</WebsiteUrl>
<InstallDir>c:\Program Files\Microsoft CRM</InstallDir>
<AdminInstallDir>\\sharedServer\crmclientinstall</AdminInstallDir>
</Client>
</CRMSetup>

I have tried various permutations of the msiexec command line, but when
it executes it just opens the windows installer but does nothing else.
Help is very much appreciated.
