Using PowerPoint to Call Excel?

[SnowDen]

I would like to have my PowerPoint presentation be able to start Excel and
run a macro on it. I would like for this to occur after a certain slide has
been reached. Is this possible?

Another approach from the excellent approach that Steve mentioned
would be to use a button on a given slide to open the Excel file and
name the Excel macro Autpen

e.g.

Option Explicit

Sub Autpen()
MsgBox "I' open."
End Sub

This will fire the macro when the worbook opens.
