CAUSE

RESOLUTION

To resolve this behavior, start the Setup program for Office. To do this, follow these steps:

Insert the Microsoft Office 2003 CD in your CD drive or DVD drive.
If the Setup program does not start automatically, locate the Setup.exe file on the CD, and then double-click the file to start Setup.
After the Setup window appears, cancel Setup, and then respond to the prompts to exit Setup.

Note You do not have to complete the Setup program. Setup fixes the error condition when it is first invoked.
