Microsoft's recent Windows updates include an update to Internet Explorer that blocks older versions of Java. If you encounter issues using Java-dependent applications after applying this Microsoft update, please update your version of Java. Instructions on how to download and install Java can be found at http://www.java.com/en/download/.
Additionally, IMSS recommends downloading and installing a custom Java configuration file on your computer. Installing this configuration file will further assist with security and compatibility with IMSS applications and it will prevent persistent, yet harmless, security warnings from appearing when using specific IMSS applications. Instructions for downloading and installing this file can be found at http://imss.caltech.edu/help/java-config-file.
IMSS would also like to remind you that you can avoid any potential Java issues with Kronos by using Kronos Limited instead, which does not require Java to run. To use Kronos Limited, go to http://kronoslimited.caltech.edu.
Lastly, note that IMSS Managed Computing customers do not need to take any action. IMSS will update Java and will install the custom configuration file for managed computers during our maintenance window on 8/21/14.
