A "runtime" error means that there is an error in a macro or add-in
that is attempting to run. Typically these macros are created by a
third-party and are not part of the Word installation. (They could
also be caused by a malfunctioning macro virus as well)

Many third-party applications will create an add-in and place it in a
Startup folder to integrate their software with Word.

Go to Tools/Templates and Add-Ins and see if there are any global
templates or add-ins listed. If you find any then chances are they are
located in your Office\Startup folder or Word\Startup folder.

The location of the Word\Startup folder can be found under
Tools/Options/File Locations and the Office\Startup folder will be
located in the installation path for Office.(You can also use Windows
Search and search for the file names)

If you find more than one add-in move them one at a time until you
determine which one is causing the problem.

When exiting Word 2003, MS Visual Basic Window appears with error
message.
Message in MS VB window reads:
"Run Time error '91': Object variable or With block variable not
set"

The "Continue" and Debug" buttons are greyed and "End" and Help
buttons
active.
Clicking "End" button terminates program.

I have not automated a MS application or developing an Office
application.
Used a workaround suggested by MS since Adobe Acrobat was not
working.
