Support for Windows XP is ending on April 8, 2014.

After April 8, 2014, technical assistance for Windows XP will no longer be available, including automatic updates that help protect your PC. If you continue to use Windows XP, your computer might become more vulnerable to security risks and viruses. 
 
An unsupported version of Windows will no longer receive software updates from Windows Update. These include security updates that can help protect your PC from harmful viruses, spyware, and other malicious software, which can steal your personal information. Windows Update also installs the latest software updates to improve the reliability of Windows—new drivers for your hardware and more.
 
Advanced Revelation will not run on workstations installed with Windows Vista, Windows 7 or Windows 8.  If you are running an application built with Advanced Revelation we strongly suggest that you consider upgrading to OpenInsight using Arev32.
