Installing Microsoft Dynamics CRM 3.0 Client silently

The steps in the IG say to use the following syntax:

msiexec /q /l c:\clientinstall.txt Client.msi CONFIG=c:\installconfig.xml

I followed the steps in the IG on page 16-3 for creating an Administrative install location for the Laptop\Desktop Client on C:\Client\Laptop shared as \\crmserver\Client.
I added my .xml file named silentinstall.xml to that same location.

I was able to get this to work using the following syntax:
msiexec.exe /i \\<myservername>\Client\Laptop\Client.msi /q /l c:\clientinstalllog.txt CONFIG=\\<myservername>\Client\Laptop\silentinstall.xml


msiexec.exe /i \\crmserver\Client\Laptop\Client.msi /q /l c:\clientinstalllog.txt CONFIG=\\crmserver\Client\Laptop\silentinstall.xml

What is important to know is that I found out that you need the AlwaysInstallElevatedenabled in the Register on machine and user level.
