Why not use late binding?

Dim oPpt As Object

Set oPpt = CreateObject("Powerpoint.Application")

etc.

Hi,

I have developed a tool in excel 2003, in which i had used powerpoint
objects (Microsoft PowerPoint 11.0 Object Library). if i open it in Excel
2002 or Excel 2000 it will give an error. is there any way to find out the
respective object library of the respective versions.

Thanks in advance.
