Content Manager & Server update Utility

Goood morning,

I am trying to 'use' Content Manager (1.0.2) to create a Server Update Utility for my PowerEdge (PE) servers.  I have already downloaded the ISO image to a folder on the E: drive.  When I try to "Create Custom Server Utility" I use Dell Online as the source and a folder on the E: drive as the destination.  When I click Next there is nothing listed in the 'Models' box.

Have I  missed something? I followed the video at (http://en.community.dell.com/techcenter/systems-management/w/wiki/1764.aspx)

Thanks
Tony
