The installation of Java can terminate on some computer systems with the error message "Error 25099 Unzipping Core Files Failed". This can happen with the Java online or offline installer. The reason for this error message is not totally clear but there are a few things that users can do to fix it to be able to install java without further problems.
The first thing that they should try is to uninstall all remains of previous Java installations. This can be done from the Windows Control Panel. The user can then try to install Java again once Java has been uninstalled and the computer rebooted. Another possibility to ensure that no traces of Java are left on the computer system is to run the excellent JavaRa software program which can remove all Java files and information from the computer.
It might happen that the error 25099 is still popping up after completely removing Java from the system. Another option to try is to check the change destination folder during installation and pick a different folder for the installation of Java.
This should fix the problem "Error 25099 Unzipping Core Files Failed" that some users have when trying to install Java on a computer running the Windows operating system.
