Re: Java Update Error
How do I install Java??
I had JDK 6 Update 17 and it was working fine.
I tried installing JDK 6 Update 24 and all I get are errors.
There were no errors on the install but it didn't install properly.
You might have a broken installer.
I've tried uninstalling, rebooting, reinstalling, it's still broken.
If I go to my Control Panel and double click on Java I get a message
titled "Java(TM) Control Panel" which says "The system cannot find the
file specified. C:\Program Files\Java\jre6\bin\javacpl.exe".
This file does not exist in that path though java.exe, javaw.exe,
javaws.exe and 43 other exe files are in that path.
Javacpl.exe exists in this path: C:\Program Files\Java\Jre6\jre\bin.
Why is Java so broken that uninstalling and reinstalling doesn't fix
I'm running this file: jdk-6u24-windows-i586.exe (Size 76.5 MB

On Windows I always remove the JRE and JDK and reboot before re-installing a
new one. I would attempt to do that and remove the whole Java directory when
you are done before installing again. The JRE will automatically update the
path, for the JDK you need to set that yourself.
On Windows I never do that. It handles multiple JRE/JDK installations just fine.
If you install the JRE in the same location as the old one, it will overwrite it.

What would be the point? Aren't you the one who said never run old
You tell me. You're the one asking how to do it.
versions because they're full of bugs and security flaws?
Isn't Java supposed to be backward compatible, if it ran on any
previous version it should run on the latest one?
My hope is that it will overwrite it, or rather replace it, to include
removing files if a newer version for some reason renamed something or
doesn't need it anymore.
Installing multiple versions with multiple paths is just a hassle if
Not really. It just looks that way because you still have unanswered questions.
Mostly you just install it wherever you need and set your envars accordingly.
I've been working with multiple simulataneous versions of Java on the same
machine under both Windows and Linux for over a decade and never had the sort
of problem you describe, nor have my coworkers over that time.
Usually it just works. Whatever is going on for you, it isn't Java's fault.
The Java installers works for millions of others, so it must be something
specific to your environment.
the new version can run everything the old one could. The path to the
JDK/JRE is hard coded into Eclipse as well as the proprietary service
we run most of our compiled jar programs in.
Eclipse does *not* hard-code the JDK path. It uses a setting in
"eclipse.ini", plus you can configure an arbitrary number of JREs within the
IDE. It has to do that because part of its purpose is to develop code for
multiple target platforms.
