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 the
Office\Startup folder or use a COM add-in (DLL) to integrate their
software with Word. Another common add-in, the "Microsoft Works Suite
Add-in for Word" can only be found in your Add/Remove programs list.
Aside from the Works Suite Add-in, to determine if you have any add-ins
you can check for them using the following:
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.
If you find more than one add-in move them one at a time until you
determine which one is causing the problem.
As of Word 2000, Word can have COM add-ins, those that are added in via
the Registry rather than the Startup folders. To check for COM add-ins
add the "COM Add-In" command to your toolbar.
- Right-click any toolbar and select Customize
- On the Commands tab, select the Tools category
- Locate COM Add-Ins on the right
- Drag/Drop to a location of your choice
