XL98: Cannot Modify Microsoft Excel 5.0 Add-in

• Microsoft Excel 98 Macintosh Edition

SYMPTOMS

In the Visual Basic Editor for Microsoft Excel 98 Macintosh Edition, when you attempt to edit a project for an add-in that is saved in the Microsoft Excel 5.0 file format, you receive the following error message:

Project is unviewable

CAUSE

When you run a Microsoft Excel 5.0 add-in in Microsoft Excel 98, the behavior of the add-in remains unchanged. However, the method that you use to edit and protect an add-in in Microsoft Excel 98 is different from the method you use in Microsoft Excel 5.0.

Add-ins that you save in a format for use with earlier versions of Microsoft Excel are protected; you cannot access the worksheets in Microsoft Excel, and you cannot access the modules in the Visual Basic Editor. These measures are used to protect the add-in being changed. Microsoft Excel uses a random password to protect the project, which prevents the add-in from being unprotected.

RESOLUTION

To edit and modify an add-in that is created in Microsoft Excel 5.0, open the source workbook used to create the add-in, and make modifications to the source. After you modify the source workbook, create a new add-in from the source workbook.

STATUS

This behavior is by design of Microsoft Excel 98.
