How to Remove Earlier Versions of OfficeWhen you install Office, Setup checks to see if any components from earlier Office versions are installed on your computer. If Setup detects these earlier components and you select any option except Upgrade in the Type of Installation pane, Setup displays the Previous Version of Office pane. If you select Remove all previous versions, Setup removes all earlier Office programs that are installed. This helps prevent unnecessary files from occupying disk space on your computer.
You can also selectively remove programs from earlier versions of Office by selecting Remove only the following application(s), and then selecting each program that you want to remove. If you remove older Office components, other programs that use these older components may not work correctly.
For example, assume that you want to install Office 2003 but previously you developed a custom program that will only work in Microsoft Access 97. To use the custom program, Access 97 must be available after you install Office 2003. Therefore, perform a Custom Install of Office 2003, select Remove only the following applications, and then click to clear the check box next to Microsoft Access (and any other programs that you want to keep).
How to Keep Earlier ProgramsUse either of the following methods to set up Office 2003 and keep earlier versions of Office programs on the same computer.
Method 1: Select "Keep All Previous Versions"Run the Office 2003 Setup program, and then select Custom Install. In the Previous Version of Office pane, select Keep all previous versions. When Setup is completed, the earlier Office programs will be available.
Note The Keep all previous versions option will only be an available option when there is not an earlier version of Microsoft Outlook installed. This issue occurs because only one version of Outlook can be installed on your computer.
Method 2: Select "Remove Only the Following Application(s)"Run the Office 2003 Setup program, and then select Custom Install. In the Previous Version of Office pane, select Remove only the following application(s), and then click to clear the check boxes of the programs that you want to keep.
