I'm afraid I don't know the answer to this, but the Microsoft Knowledge Base
article at http://support.microsoft.com/kb/827467 describes the error. Were
you logged in as Administrator when you tried to do this?

Equation Editor is part of all versions of Word but is not installed by
default (as part of the "Typical" install). If it is installed, you will
see Microsoft Equation 3.0 listed under Insert | Object | Create from
File. If not, install it as follows:

Go to Control Panel | Add/Remove Programs, select Microsoft Office, and
click the Change button. In the first page, select "Add or Remove
Features."
On the next page, expand "Office Tools." Select Equation Editor and set
it
The next choice shows check boxes for Word, Excel, Outlook, ... Access. It
says if I uncheck any, the will be removed. Pushing ahead with the Update
button produces "error 25090. Off setup has encounered a problem with the
Office Source Engine, ...Please open C:\Program Files,....chm and look for
the Office Source Engine on how to resolve this."

I wouldn't mind uninstalling Outlook and Publisher, if it would get by
this error. I never use them.
to "Run from My Computer." Click the Update button, and insert the Office
CD
when prompted.

Once it is installed, you may want to add a toolbar button to launch it
quickly; in Tools | Customize | Commands, look for Equation Editor in the
Insert category and drag it to the preferred toolbar.
