SYMPTOMS

When you run Setup for an upgrade version of Office XP, you may receive the following error message:
Error 25003. Microsoft Office setup cannot continue because the installation source has been corrupted.

CAUSE

This behavior occurs if all the following are true:
  1. You run Setup by using an upgrade version of Office XP on a computer that does not have a qualifying Office upgrade product.
  2. In the Product Compliance Check dialog box, you click the Drive list and then select your CD-ROM drive.
  3. You eject the Office XP CD, insert the CD for a qualifying Office 97 or Office 2000 product, and then click OK.
  4. After the qualifying product is detected, you continue the Office XP installation, with the CD for a qualifying Office product still in the drive.
The Windows Installer is tryin to use the CD for a qualifying Office product. Because this is not an Office XP CD, the Windows Installer cannot locate the necessary files for the Office XP installation.
