Cannot uninstall previous versions of Java 2

[Uncle Scotty]

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

To remove the Microsoft JVM, perform the following steps:

Copy and paste the below line into the Start, Run box:

RunDll32 advpack.dll,LaunchINFSection java.inf,UnInstall

Click Yes to the confirmation, then select Reboot.
After the machine restarts, delete the following items:
1 - the \%systemroot%\java folder
2 - java.pnf from the \%systemroot%\inf folder
3 - jview.exe and wjview.exe from the \%systemroot%\system32 folder
4 - The HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Java VM registry subkey
5 - The HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AdvancedOptions\JAVA_VM registry
subkey (to remove the Microsoft Internet Explorer (IE) options)

Microsoft Java is now removed.

You can download Sun's newer JVM for Windows at http://java.sun.com/getjava/index.html.

Delete Old Versions of Java ?

Is it ok to just leave the old versions on the machine?

I have the folllowing versions installed, should I uninstall any?

full name:
Sun Microsystems, Inc. - Java(TM) 2 Platform Standard Edition 5.0 Update 4
Version 5.0.40.5 *
Sun Microsystems, Inc. - Java(TM) 2 Platform Standard Edition 5.0 Update 6
Version 5.0.60.5 *
Sun Microsystems, Inc. - Java(TM) 2 Platform Standard Edition 5.0 Update 7
Version 5.0.70.3 *
etc..

Names as they appear in add /remove:
J2SE Runtime Enviroment 5.0
J2SE Runtime Enviroment 5.0 Update 4
J2SE Runtime Enviroment 5.0 Update 6
J2SE Runtime Enviroment 5.0 Update 7
Java2 Runtime Enviroment SE v1.4.2_05

By the way did I miss update 1-3 and 5 ?

Are updates "inclusive", that is update 7 does that include in it updates 1
to 6 ?

Thanks for your feedback. when you say "\%systemroot%\", is that the
equivalent of "c:\"? How does one delete registration keys, through
regedit? Is there any potential gotchas to watch out for? Playing with
the registry makes me a little nervous.

And, lastly, does this instruction delete all previous versions of the
JVM or do you have to delete them one at a time as you would with
Add/Remove programs? I also have the current JVM now installed and hope
that wouldn't remove this JVM...

 

[Uncle Scotty]

Sure, it won't hurt things in theory, but it does take up quite a bit
of space on your machine, so having too many Java environments on your
machine could slow things up over time...

Thanks Uncle Scotty,

I will start spring cleaning and tidy up my machine.
