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

No it's not correct. If it was, than you wouldn't ask here. ;) You have to Combine (Windows Server AND some rule to determine if JAVA is already installed) and put this in OR together with Windows Workstation and the MSI Not installed.

I'll try later something. But Davids rule Looks pretty much the same way, I would've configured it.
