A: The automatic update feature works only on Windows 2000 with SP3 and WindowsXP. If you are running on one of the other supported operating system, this feature will not work. If you want to do an update, use the Update Now button for manually updating Java.
A: The Java installer is designed for Install On Demand. It will download more installer files based on user selection and system configuration. Using this installer helps users avoid downloading large amounts of unnecessary files.
A: Rebooting is sometimes required because installing Windows Installer 2.0 the Microsoft technology used by the Java installer requires rebooting.
Note: Java Installer now detects Java enabled Mozilla browsers locked files and will prompt you to close the browser so that a reboot can be avoided.
A: You need to close and restart the Java Control Panel to get the updated Control Panel.
A: First close all the browsers sessions. If this does not work, reboot the system and try again.
D:\ drive and Java Update is still installing files onto the
C:\ drive. Why?
A: Regardless of whether an alternate target directory was selected, Java Update needs to install some update files on the Windows system drive . Doing so saves download time on future updates to the latest version of Java.
A: There are two ways to accomplish this:
If you want to uninstall the JRE, use the "Add/Remove Programs" utility in the Microsoft Windows Control Panel (Start->Settings->Control Panel to get to "Add/Remove Programs").
Alternatively, if you still have the original installation program that you used to install the JRE, you can double-click on it. This will take you to a screen with Modify and Remove options. Select Remove to uninstall the JRE. Note that you must be connected to the Internet for this to work.
A: The JRE bootstrap installer uses the system Internet Connection settings to connect to the web for downloading extra files. If you are behind a firewall and require proxy settings, make sure the proxy settings in Internet Options/Internet Properties are set up properly (Start->Control Panel->Internet Options/Internet Properties->Connections->LAN Settings ...).
If you can browser the external web (i.e., outside the firewall) with Internet Explorer, then your proxy settings are properly set up. The installer doesn't understand the proxy settings specified in Netscape/Mozilla.
jusched.exe—running in the background of my system after installing JRE. Is there a way to shut them down?
jusched.exe is the scheduler process of Java Update;
jucheck.exe is the process for checking/performing updates in Java Update. These processes run automatically and transparently to users. To shutdown these processes, simply uncheck the "Check for Updates Automatically" checkbox in the Update tab of Java Control Panel.
A: If you installed the JRE through the Custom option but unchecked the browser selections, you may run into this situation. To fix the problem, go to the Browser tab in Java Control Panel and check the browsers that you want to run the newly installed version of Java.
A: Java Update can only be run if the system is connected to the network. A system that is not connected to the network is referred to as being "offline". When the Update Now button is clicked, it will check the online/offline status of your system. If your system is not currently connected to the network or dial-up networking is disconnected, the error message will show up. Check that your system is currently connected to the network and try it again.
A: The message is part of the Java Auto Update mechanism, which detects at user login time if a newer version of the JRE is available for download . You may simply click on the system tray Java Update icon to download and install the update.
A: You may want to backup your Windows registry before testing out Java Update. The following command will export the necessary registry keys to a file:
regedit -e reg.1 -t HKEY_LOCAL_MACHINE
regedit -e reg.2 -t HKEY_CURRENT_USER
regedit -e reg.3 -t HKEY_CLASSES_ROOT
To fully restore the registry keys, the following command can be used to import the exported registry values:
regedit -i reg.1
regedit -i reg.2
regedit -i reg.3
A: This problem occurs when the server is too busy or when the network is too congested to serve the file. Please retry by running the installer again.
A: There are several possible reasons:
To address these problems, please make sure third-party downloader/TSR programs are turned off and the network connection is setup properly. Also, if a proxy is in use, make sure that proxy authentication is turned off.
A: This is a known MSI engine problem. See following:
