Java SE (Java Platform, Standard Edition)

I am able to install the 1.4.2_02-b03 JRE package on Windows 2000 Pro (SP4).

However, the 1.4.2_02-b03 SDK package does not install: some way through the process (the file copy stage) a modal dialog is displayed ("Warning - Java(TM) Update
---------------------------
Java(TM) Update (1.4.2_02-b03) cannot be installed on this machine because the Java(TM) Virtual Machine is currently running.

Please close all running Java(TM) applications, especially browsers.

---------------------------") and when Cancel is clicked, the main MSI installer program displays an Error 1722 modal dialog ("A program failed to execute blah blah...") and the MSI program announces installation has failed, nothing has been installed, and so on.

The MSI log in the temp directory displays "Error 1722.There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action patchsdk, location: C:\Program Files\Common Files\Java\Update\Base Images\j2sdk1.4.2-b28\patch-j2sdk1.4.2_02-b03\patchsdk.exe, command: -s "C:\Programs\Java\SDK\"
=== Logging stopped: 06/11/2003 23:53:02 ===
"

Examination of the installation directory (C:\Programs\Java\SDK in my case) shows that program files have been copied (and it looks complete), but the Java applet in the Control Panel does not show that the JRE in the SDK directory has been registered as a JRE choice (normally it is in the drop-down list of available JREs).

So what can I do? Both 1.4.2_01 SDK and 1.4.2_02 SDK show this problem; 1.4.2 (FCS) does not. The problem also occurs with the IFTW installers.
