Uninstall all Previous Windows Versions of JRE

Post by mthom1048 » Thu, 01 Jul 2004 00:36:29

Help! I am working on a corporate deployment of JRE V1.4.2_04. I
would like to programmatically uninstall all previous versions of
Java. Is there an easier way to manually remove all previous versions
without having to:

1) Enumerate all Uninstall registry keys in Registry
2) Kicking off uninstall strings (create response files if necessary)

This approach is messy and I have no way of knowing all previous
versions of SUN JRE released.

Should I leave existing versions on the workstation? I would like to
keep a corporate standard. Any help on this topic would be GREATLY
appreciated. Thanks.

1. Uninstalling a previous version of Windows

2. uninstall windows and revert to previous OS version

I have Windows Server 2003 installed in a machine, and need to uninstall it
and revert to Windows 2000. I know I sent this question to different OS
group, but I think it can apply since the logic should be similar.

First, I make sure CDRom is the first boot device in BIOS setting. Then, I
inserted Windows 2000 CD and attempted to boot from CD, and re-format the
hard disk and install from there. Unfortunately, it still loads Windows
Server 2003, and then pop up an error message dialog saying "The CDRom is
from an older version of windows than the one you are presently using. setup
functionality is disabled." Any ideas??
