From Microsoft:

To fix this problem, you might need to restart the Office Source Engine (OSE) service and try to install the latest updates for Office products again.

To restart the Office Source Engine (OSE) service

You must be logged on as an administrator to perform these steps.

1. Open Administrative Tools by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Administrative Tools.

2. Double-click Services. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3. If the Office Source Engine service is disabled, double-click it to open the service properties.

4. Click the Startup type list, click Automatic (Delayed Start), and then click Apply.

1. Go to Start Menu > Run (or Windows + R from your keyboard)

2. Type regedit

3. Find these entries

HKEY_CURRENT_USER\Software\Microsoft\Office11.0 (or 12.0)

HKEY_LOCAL_MACHINE\Software\Microsoft\Office11.0

4. Right-click on each of the entries and choose Rename. You can rename it to whatever name you like, for example, BlahOffice11.0

The point here is that by renaming the registry into another one, the MS Office installer will consider the installation as a fresh install in which you have no previous MS Office installed so that it will simply go with the default installation process.

5. Restart your computer

After restarting your computer, you may begin installing MS Office 2003 from your CD smoothly.
