Why?A: First close all the browsers sessions. If this does not work, reboot the system and try again.I try to install on the 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.How can I uninstall the Java Update version I just installed?If you want to uninstall the JRE, use the "Add/Remove Programs" utility in the Microsoft Windows Control Panel (select Start, then Settings, then Control Panel to get to "Add/Remove Programs").After the JRE bootstrap installer is downloaded and executed, why does the message "This installer cannot proceed with the current Internet Connection settings of your system. In your Windows Control Panel, please check Internet Options -> Connections to make sure the settings and proxy information are correct." appear?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 (select Start, then Control Panel, then Internet Options/Internet Properties, then Connections, then LAN Settings)If you can browser the external web (for example, outside the firewall) with Internet Explorer, then your proxy settings are properly set up. The installer does not understand the proxy settings specified in Netscape/Mozilla.I found two processes jucheck.exe and jusched.exe running in the background of my system after installing JRE. Is there a way to shut them down?A: jusched.exe is the scheduler process of Java Update; jucheck.exe is the process for checking/performing updates in Java Update.
