Deploy Java via SCCM ?

We need to upgrade several hundred PC's via SCCM 2007 with the latest Java edition-7 Update 25.  Most are Windows 7 64-Bit systems (and a few XP 32-Bit systems).  We only need to install the 32 bit Java version.  I looked online a few places for the best solution, and couldn’t necessarily find anything. A few questions:

1. Do I need to uninstall the old version before installing the new one?  Or when the new one installs will it automatically remove the old one?  Will a new version just install 'on top of' the old one?

2.  Will settings migrate from their old version to the newly installed version?

3.  I heard that if a user’s IE or Firefox browser is open, the install will hang.  For most people to get around this, they have tried scripting solutions to terminate the browser.  What about just running the installer when a user logs in?  Any issues there?

4.  Any specific switches or options that need to be set on the command line installer when it runs?

Hi

1) Yes you need to uninstall the old version. Leaving it is a security hole waiting to happen

2) Settings will migrate but you're uninstalling. Also Oracle have a habit to change settings files so it's better not assume the settings from before will be fine

3) yes - installing/uninstalling with IE open will cause problems. You can automatically close (terminate IEXPLORE.exe process) with a script OR pop a message up and not progress until obeyed!

4) switches are REBOOT=ReallySupress JAVAUPDATE=0  AUTOUPDATECHECK=0

Note  these parameters are case sensitive (they public properties for the MSI)

A good walkthrough is here.

There was another great guide for installing Java here on EE but I can't remember if the site above was it. Still this is good too. Particular note is the uninstall GUIDs at the end of the article.
