When I try to download Java, I get the error message #25099 - Error unzipping core files. The fix tells me to remove C:Program FilesJavajre6. However, I cannot locate this file anywhere to remove it. Can you help?

If you are getting that error, it means that eitherJava is not installed, or is not in your path. 
If Java is not installed, go to http://www.java.com to install the most recent version of the JRE. 
If you're sure you have already installed Java ensure the Java executable is in your system's path. You can do this by first finding the directory it is installed in. For example, mine is installed in C:Program FilesJavajre6. The executables are located in the bin directory. 
In order to set your path (Assuming Windows Vista), go to Start -> Control Panel -> System, then click on the 'Advanced System Settings' link on the left, then the 'Environment Variables' button. In the lower section (Labeled 'System Variables'), scroll through and find the item labeled 'Path' and double click it. In the field labeled 'Variable value' go to the end and add a semicolon (;), and then the path your installation of Java is located. Using the example I gave above, I would have added ;C:Program FilesJavajre6in to the end of the line. 

The procedure for 64-bit Windows Vista or Windows 7 is the same, except the text you will add to the Path variable is ";C:Program Files (x86)Javajre6in". Notice there is still a semi-colon at the beginning of the line. 

Once you have done this, you will need to close and reopen the command prompt if it is already open, and you should be able to run java without getting this error message.

Hi! the error it self highlighting "regular uitlity" concept in dll name. there is no problem with automatic java updates, but may be missed connection of updates path, so try think about it there would be no problem at all with java updates and operating system..

What version of Java do you have running? Have you tried uninstalling the JVM (add/remove software in control panel) and re-loading from the most current version from Sun? V6.16 is most current:

http://www.java.com/en/download/index.jsp

make sure the %ProgramFiles%\Java\jre6\ and %APPDATA%\Sun\Java\jre1.6.0_10\ directories are empty. and than try to reinstall it.

Another solution is to download the complete update, and manually install. Therefore bypassing the incremental download situation, and further determining if it is a legitimate software bug, or corrupted incremental download packets.

i.e. Download and install the redistributable package from Sun..
