Hi Christie,

http://support.microsoft.com/default...b;en-us;827467

SYMPTOMS
When you try to start a Microsoft Office 2003 program, you may receive the
following error message or an error message that is similar to the
following:

Error 25090. Office Setup encountered a problem with the Office Source
Engine, system error: -2147023836. Please open SETUP.CHM and look for
"Office Source Engine" for information on how to resolve this problem.

CAUSE
This behavior occurs when the following conditions are true:
Two people installed Office 2003 on the same computer.
Both installations were completed by using the AllUsers="" parameter to set
the installation for the installing user account only.
When both people were prompted to remove files that were copied locally at
the end of Setup, both people did not remove the files.
One of the two people removed Office 2003.

RESOLUTION
To resolve this behavior, start the Setup program for Office 2003. 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.

Please let me know has this helped you...

Thank you,
Raghu...
