New Post: Install on Clients, but only update on Servers

Yes, with Davids examples the Servers still try to install it, without having it installed.

The Point with the exact Version:
Yes I know, but we have:
13 Different Versions of Java 6
18 Different Versions of Java 7
4 Different Versions of Java 8

Is my last Syntax correct and matches now: "Logic for And/Or groups apply IN the group itself."?

Thanks, Martin
