Does anyone out there have any experience populating a pdf file using the 
FDF toolkit from Adobe from an ASP.Net page? I am using the following 
code, but it is blowing up on the line shown, which is a method call 
required by the FDF toolkit:

<%@ Import Namespace="System.Runtime.InteropServices" %>
<%@ Page Language="vb" AutoEventWireup="false" aspcompat=true 
Inherits="CLIPSLink.eSignPrintMPN"%>
 
<%
Dim objFDF as object
objFDF = server.CreateObject("FdfApp.fdfapp")
 
Dim objFDFOut as object
objFDFOut = objFDF.FDFCreate   '<<======= LIBRARY NOT REGISTERED ERROR 
OCCURS ON THIS LINE
 
objFDFOut.FDFSetValue("LastName", "Wilson", False)

This method call works fine with classic ASP, but not with .Net.
