Novell released a MSI package for the Zenworks 7.5 Asset Management Client.

The self extracting archive file 'zam750clientmsi.exe' contains a 'ZENworks Asset Management - Client Applications.msi'. The only thing you will have to do to deploy this package is by configuring a couple of MSI properties:

INSTALLDIR="C:\Program Files\ZAM"
an optional property to configure where to install the ZAM program files, the default is 'C:\Program Files\Novell\ZENworks\Asset Management\bin'

HOSTNAME="RVBAM01"
a mandatory property to configure to the IP address or DNS hostname of the ZAM host the client should connect to

LOCALPORT="7461"
the local port being used by the ZAM client, the default port = '7461'

REMOTEPORT="7460"
the remote port being used by the ZAM server, the default port = '7460'

 Test this MSI and Transform file by using msiexec /i "ZENworks Asset Management - Client Applications.msi" TRANSFORMS="ZENworks Asset Management - Client Applications.msi"  /qb

If the testing was successful, create a ZENworks 'Install Only" application object and distribute it to your users. The ZENworks Asset Management client is running as a service: 

This is how the 'Program Files' directory looks like:
