We have an Excel 2002 worksheet that is using the Internet Assistant VBA
add-in. We make
a reference to this add-in in VBA and use this to save certain ranges of the
workbook as HTML
files.

The issue that pops up is if someone opens this workbook and they don't have
this add-in loaded
(i.e. the box is checked in the add-ins dialog box), they'll get a compile
error. We tried using
code to in VBA to install the add-in (Addins.Add...), but since the error
comes up when the
workbook is first loaded, this code doesn't get a chance to run (we have it
in the procedure that is
writing out the HTML).

Is there a way to do a type of late-binding to reference an add-in in Excel
2002?

Thanks
