Installation instructions
To install this update, do one of the following:

• Use Microsoft Update (recommended). Microsoft Update consolidates updates provided by Windows Update and Office Update into one location and enables you to choose automatic delivery and installation of high-priority updates.
• Use Office Update on the Office Online Web site. After running the automatic detection, Office Update prompts you to install updates and service packs that bring your Office products up to the best quality available. Office Update is not supported on Windows Vista.
• Install only Office 2003 SP3. To do this, follow these steps:
  • Download the file Office2003SP3-kb923618-FullFile-enu.exe by clicking the Download button at the top of this page. Save the file to your hard disk drive.
  • It is recommended that you quit any programs you are running.
  • In Windows Explorer, double-click the .exe file that you saved to your hard disk drive, and follow the instructions on the screen.

SP3 will install even if a publicly available update has already been installed on your computer.
