If it finds another instance of Word, it will give you the option of closing one instance or allowing the new instance.
   Sub AutoExec()
      Dim tApp As Task
      ' Loop through all running applications.
      For Each tApp In Tasks
         ' If application is Word...
         If InStr(1, tApp.Name, "Microsoft Word") Then
            ' Display choice to close or not close
            Select Case MsgBox("Close (" & tApp.Name & ")?", vbYesNoCancel)
               Case vbYes
                  ' Switch to the Word instance in case a dialog box or
                  ' message is being displayed that prevents you from
                  ' closing the instance of Word.
               Case vbCancel
                  Exit For
               Case Else
            End Select
         End If
   End Sub
