Installation Server 710

Hi all, we are attempting to install the SAP Installation Server for the first time and are having some problems.

We have the installation server installed and have created a package for SAP GUI 710 COMP 2 and added patch 7.

When I run the silent install from a client -
server\share\Setup\NwSapSetup.exe /Silent /Package="GUI2"

all the files install but nothing happens when the user double clicks the SAP Logon icon.

The Error log on the client states that "The system cannot find the patch specified" for numerous files, yet all these files are on the client.

The permissions seem ok and this client is a full admin.

Any ideas?

Thanks!
