Cannot uninstall previous versions of Java 2

Hi,

When I try to uninstall various components of JAVA 2 v 1.4.2_0x, I get
the following error message:

Error 1316. A network error occurred while attempting
to read from the file C:\WINDOWS\Installer\Java 2 Runtime Environment,
SE v 1.4.2_03.msi

These are the various installed components that I want to get rid of
since I know have v 1.5 installed on my machine and want to use that
RE:

Java 2 Runtime Environment, SE v 1.4.2_03
Java 2 Runtime Environment, SE v 1.4.2_09
JAVA 2 SDK, SE v 1.4.2_09

Any help as to how to remove them from my computer?

Thanks, Scott
