When you run the 2007 Microsoft Office Setup program on a computer on which earlier versions of Microsoft Office are installed, the earlier versions of Office are removed. Additionally, you may not receive a message that states that this has occurred.

Note When you click Upgrade in the Microsoft Office suite_name 2007 Setup program dialog box, you may see the following description:

This issue occurs because earlier versions of Office are automatically removed when you click Upgrade in the Microsoft Office suite_name 2007 Setup program dialog box. This automatic removal occurs by default.

When you click Custom in the Microsoft Office suite_name 2007 Setup program dialog box, the Custom setup dialog box opens. When you click the Upgrade tab, you see the following options:

•	Remove all previous versions
•	Keep all previous versions
•	Remove only the following applications

Also, each installed program from an earlier version of Office is listed in the Upgrade tab. There is a check box next to each program name. When you upgrade to the 2007 Office suite, the Office Setup program targets the following versions of Office programs for removal:

•	All versions of Microsoft Office 2000
•	All versions of Microsoft Office XP
•	All versions of Microsoft Office 2003
•	Microsoft Works Suite 2000
•	Microsoft Works Suite 2001
•	Microsoft Works Suite 2002
•	Microsoft Works Suite 2003
•	Microsoft Works Suite 2004
•	Microsoft Works Suite 2005
•	Microsoft Works Suite 2006

Versions of Office, of Works, and of Works Suite that are not listed must be removed by using the Add or Remove Programs feature in Control Panel.

Note Although we do not recommend this configuration, you can install and use more than one version of Office on a single computer. For example, you can install and use both Office 2003 and the 2007 Office suite on the same computer.

How to remove earlier versions of Office programs

When you install Office, the Setup program verifies whether any components from earlier Office versions are installed on your computer. If the Setup program detects these earlier components, and if you select any option except Upgrade in the Microsoft Office suite_name 2007 Setup program dialog box, the Setup program displays the Upgrade tab. If you select Remove all previous versions, the Setup program 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. To do this, select the Remove only the following applications option in the Microsoft Office suite_name 2007 Setup program dialog box. Then, select each program that you want to remove.

Note 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 the 2007 Office suite. You previously developed a custom program that will work only in Microsoft Access 2002. To use the custom program, Access 2002 must be available after you install the 2007 Office suite. Therefore, you must click Custom in the Microsoft Office suite_name 2007 Setup program dialog box, click the Upgrade tab, and then click to clear the check box next to Access 2002 (and any other programs that you want to keep).
