In Microsoft Excel 97, when you run a Visual Basic for Applications macro, and then attempt to access a demand-loaded add-in, you receive an error message, and then Microsoft Excel quits.

   generated.

CAUSE

This problem occurs when the following conditions are true:

      -and-
  

• You access a demand-loaded add-in while no workbooks are open in Microsoft Excel.

WORKAROUND

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

"Demand-loaded" means that an add-in is set up for use in Microsoft Excel; functionality in the add-in is available dialog boxes and menus, but the add-in file is not actually loaded into random access memory (RAM) until the functionality is requested. Demand loading an add-in requires less time than fully loading the add-in into RAM.

You may experience the problem that is described in this article when you access one of the demand-loaded add-ins in the following list:

   AutoSave
   Conditional Sum
   File Conversion Wizard
   Internet Assistant Wizard
   Lookup Wizard
   Report Manager
   Solver
   Template Wizard with Data Tracking
   Web Form Wizard
