Installing Internet Express Software Update Packages

Most updates for Microsoft® Office applications are released as Windows Installer-based MSP files contained in self-executing download files (EXE files). The EXE files, which are released in both a full-file and binary version, can be run directly on client computers. Alternatively, the MSP files can be extracted and applied to either an administrative image or client computers.

In a few scenarios, however, the most efficient way to update the client is to bypass Windows Installer and copy new files directly on top of existing files by using Internet Express (IExpress) software update packages. Unlike Windows Installer patches, IExpress client patches do not contain MSP files; they are EXE files that must be run on each client computer to be applied.

If you installed Office from an administrative installation point, you cannot apply an IExpress update to the administrative image. Instead, you should save the EXE file on a file server and use one of the following methods to distribute the update to clients:

  • Write a log-on script that applies the patch to each client computer the next time the user logs on.
  • Use software distribution software, such as Microsoft Systems Management Server or Tivoli, to run a script that applies the patch to each client.
  • Distribute a command line, batch file, or link to the EXE file in an e-mail message.

Occasionally, an IExpress software update package is included in a service pack. When users run the EXE program for the service pack, the IExpress package also runs. However, if you extract the MSP file from the service pack and distribute it to users, then the IExpress package is typically left behind. In this case, you must use one of the methods described previously to distribute the IExpress update separately.

Users who install Office from an updated administrative image in the future must also install the IExpress patches separately. If you are supporting Office 2003 or Office XP users, you can chain the EXE files in the Setup.ini file; if you are supporting Office 2000 users, you can write a batch file that distributes and runs the patches on client computers. Alternatively, you can use the Custom Installation Wizard to create a transform (MST file) that runs the patch installation program when Office is installed.

Each IExpress software update has a corresponding article in the Microsoft Knowledge Base. Search the Knowledge Base Check the article referenced with the update for a list of command-line options and other details specific to that update.
