Hi, Soul 786,
Unfortunately, that's a rather vague error message that could be caused by
one of many possible things. There's a good article here with a boatload of
things to try when you get that error:
How to troubleshoot failures updating your Office installation from the
Office Update Web site:

If you are running Windows Installer 3.0, this might be the cause:
You receive an "Error 2902. An internal error has occurred" error message or
an "Installation unsuccessful" error message when you install an Office 2003
update on a computer that has Windows Installer 3.0 installed:

Hope one of those helps--
