MORE INFORMATION
The Microsoft Windows Installer is designed to remove previous versions of Microsoft Office if the installations are in the default path that Office uses. In some organizations, there is a need to maintain an existing installation of Outlook while installing Office.
To maintain an existing installation of Outlook, it is necessary to perform a custom installation, selecting a different path for the Office XP installation.
Windows Installer Detection
NOTE: The options listed below are not presented to the user during the Setup process if a typical installation is selected. Previous versions of Office are removed without prompting. These options are available only with a custom installation.
When the Windows Installer is first run, it detects earlier versions of Office. If earlier versions are found during this process, the
Removing Previous Versions dialog box appears. A list of previous versions is displayed along with two information messages. The following is the first message that you receive:
Setup will remove the following previous versions of Office programs.
Followed by the second message:
To keep these applications, please click the Back button and change your Office installation directory.
If you continue to click
Next to advance through the various Setup options without making the suggested alterations to your Setup path, all previous versions of Office programs are removed.
NOTE: The following is the default path for Microsoft Office 97, Setup for Microsoft Outlook 97, the Windows Installer for Microsoft Office 2000, and Active Setup for Microsoft Outlook 98:
C:\Program Files\Microsoft Office\Office
For Office XP, the default path is:
C:\Program Files\Microsoft Office\Office10
How to Maintain an Existing Outlook Installation
To customize the path for the Office installation, alter the default path in the
Microsoft Office XP Installation dialog box. Specify a path different from the one that is used by the currently installed version of Outlook.
If you proceed beyond this point, you may use the
Back button to return to the
Microsoft Office XP Installation dialog box. It is possible that the default path was not used in either installation. The key to successfully maintain either Outlook 97 or Outlook 98 is the selection of a different path for Office XP.
