If You Install by Using Office 97 SR-2 Compact Disc

If you use the complete Microsoft Office 97 Standard or Microsoft Office 97 Professional Edition compact disc version of SR-2, you must choose not to install Outlook during the initial stages of the SR-2 Setup. Microsoft Office 97 SR-2 installs updates designed for Microsoft Outlook 97. If you've already upgraded to Microsoft Outlook 98, you should perform a Custom installation of Microsoft Office 97 SR-2 and not choose Microsoft Outlook. In other words, click the Custom button on the Microsoft Office 97 Setup dialog box, and then click to clear (uncheck) the check box for Microsoft Outlook.
