Installing SMS Advanced Client

[Zoom7000]

When our network was setup the engineer setup a share on our server that had the SMS Advanced Client and we simply ran the Client.msi from the share (\\Server\GPOSMS) and it installed the SMS Client happily. Silently and without any interaction. A policy was also setup that new PCs would install SMS once they ran the policy for the first time. Simply by Active Directory deployment.

The first image shows the GPOSMS share. The second image shows a share that was presumably created when we installed SMS SP1. However, albeit it looks similar, the client.msi doesn't install silently and requires "Next" to be pressed twice and then finish. I've never deployed using group policy before, so I'd like to know 2 things:

1) Why does the installation not behave like the client.msi in the GPOSMS which is totally silent and only displays a progress windows.

2) How can I get the updated client.msi to deploy using group policy silently?

I've tried reading Microsoft's documentation on installing the client, but I'm lost!

Mr Engineer didn't produce an MST file for said client did he?

Another thing to check is if the installation for the client has changed.

Thirdly, running the GPO setup per machine rather than per user usually does not require interaction... might be worth checking this.

No, I'm pretty sure no MST has been created. Because there isn't one there. Also, the Installation is done per machine. Not per user.

How do I check if the installation has changed?

run file 1 by double clicking on it, see if you are prompted for anything... run file 2 and see if it works differently.
