System Files Update

  • Article

Office XP requires a specific version level of a set of .dll files and other shared and system files. Before installing Office XP on computers running Windows NT Server 4.0 SP6a, Windows NT Workstation 4.0 SP6a, or Windows 98, Setup verifies that these key system files are current. If they are not, Setup updates the necessary files by running the System Files Update (SFU).

Key system files and components in the SFU include the following:

  • Internet Explorer 5.01

  • HTML Help

  • Microsoft Data Access Components 2.5

  • Microsoft Visual Basic® for Applications Runtime

  • Microsoft Visual C Runtime

  • Microsoft Foundation Class 4.2

By default, SFU installs Internet Explorer 5.01 on clients running Windows 98, Windows NT Server 4.0 SP6a, or Windows NT Workstation 4.0 SP6a. If you do not want to install Internet Explorer 5.01 on these clients, you can turn off the default Internet Explorer installation by using the Custom Installation Wizard. For information about the Custom Installation Wizard, see the "Customizing Your Office XP Installation" section later in this appendix, or see the Microsoft Office XP Resource Kit athttps://www.microsoft.com/office/ork/xp/default.htm.

Note the following:

  • Whenever SFU is run on a computer, a restart is required, even if no files were updated.

  • Office XP does not install Internet Explorer on clients that are running Windows 2000 Professional, Windows 2000 Server, or later operating system versions, because Internet Explorer 5.01 is already included with these operating systems.

  • Office 2000 Public Update 1 and later includes SFU. Upgrades from this version to Office XP do not have SFU issues.
