Hi

I accidently uninstalled Java Runtime environment. No my LimeWire Pro will not start.

I have followed the links to Java Runtime from www.java.sun.com/getjava/download however despite several attempts it fails to install completely, rendering my Limewire inactive.

Has anyone else, foolish enough to go through this scenario and solved the problem.

Please feel free to either me direct to in this forum.

Any help is greatly appreciated

I had problems w/ Java (still do), and someone kindly wrote this to help me out. I was trying to get LW to use Java 1.5.0. It didn't work for me, but I think it will in your scenario.

Limewire will use the default JRE configured in your Java control panel.

Be sure, once you have installed your new version of Java 1.5 Beta 1 that this is effectively the selected JRE. You may have several JREs on your host, and the default selected one is not working properly. So select the new one, and drop the previous JRE from its directory.

If this still does not work, make uninstall all the JREs you can find in your Control Panel-Add/Remove programs, then look onto your PC to remove the Program Files\Java\ folder you may have.

Note that there may be a JRE folder within your Limewire installation directory, if you used the international installer.

Then CTRL+ALT+DEL to display the list of running app: kill the jupdate.exe process (this is the Java autoupdate tool in your system tray).

Then go to the registry and delete the following keys:

HKEY_CURRENT_USER\Software\JavaSoft\Java Runtime Environment

(this drops your Java user settings).

HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment

(this kills all your configured JREs: this key contains one subkey for each installed JRE, each subkey containing the location of its installation folder)

HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in

(this kills the integration of Java into your browser)

HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Update

(this kills the autoupdate settings and cached data)

HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Web Start

(this kills the Java Web Start installation)


Then reinstall Java. It will restore the previous keys to their default, and you'll be sure to use the appropriate version which will be the only one "supported" on your system.

Normally you don't need to reinstall Limewire because its launcher will detect and use the default JRE you have just reconfigured in a clean state.

You may want to have two versions of the JRE on your system: don't mix them into the same installation folder. Normally the Java installer proposes you a installation folder name that includes its version number. Keep that version number in the installation directory.

Never overwrite an existing JRE installation folder with another version. You may switch from one to the other using the Java Control Panel. If the last version just fits your needs, you can safely uninstall the previous version.

"Want to enhance your LimeWire experience? Our current version of LimeWire ships with Java 1.3. We encourage LimeWire users to install Java 1.4 which helps LimeWire work better with your computer. (Windows and Linux users only.) Download the Java 1.4 installer."

Why? Why ship "new" updates with outdated Java?
