"Installation source has been corrupted" error message when you install Office 2003

When you install Microsoft Office 2003, you may receive the following error message:

This problem may be caused by an incorrect version of the Microsoft XML Parser (MSXML) program installed on your computer. This is typically installed with Microsoft Internet Explorer 6 and comes preinstalled on Microsoft Windows XP-based computers. By repairing or reinstalling Internet Explorer 6, you can repair MSXML.

Note By default, Internet Explorer 6 is preinstalled in all versions of Windows XP. To provide computer manufacturers more flexibility in configuring desktop versions of Windows XP, Microsoft has made it possible for OEMs, administrators, and users to remove user access to Internet Explorer while leaving the Internet Explorer code intact and fully functional to ensure the functionality of programs and operating system functions that rely on it. For example, Windows XP supports an IEAccess=off switch in the Unattend.txt file, and Internet Explorer has been added to the Add/Remove Windows Components section of the Add/Remove Programs tool in Control Panel.

To resolve this problem, use the following methods in the order in which they are presented.
