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.
This behavior occurs if all the following are true:
You run Setup by using an upgrade version of Office XP on a computer that does not have a qualifying Office upgrade product.
In the Product Compliance Check dialog box, you click the Drive list and then select your CD-ROM drive.
You eject the Office XP CD, insert the CD for a qualifying Office 97 or Office 2000 product, and then click OK.
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.
To resolve this problem, follow these steps:
With the error message displayed on your computer, eject the Office 97 CD or Office 2000 CD from your CD-ROM drive.
Insert your Office XP CD.
Click Retry in the dialog box that displays the error message.
