Reflowable HTML generation fails

here is my code

using System;
using pdftron;
using pdftron.Common;
using pdftron.PDF;
namespace ConsoleApplication1
    class Program
        static void Main(string[] args)
           // pdftron.PDFNet.Initialize();
            // Relative path to the folder containing test files.
            const string inputPath = @"C:\Users\xxx\Documents\Visual Studio 2015\Projects\ConsoleApplication1\ConsoleApplication1\testinput\1.pdf";
            const string outputPath = @"C:\Users\xxx\Documents\Visual Studio 2015\Projects\ConsoleApplication1\ConsoleApplication1\testoutput\newsletter";
                using (PDFDoc doc = new PDFDoc(inputPath))
                    Console.WriteLine("Converting PDF file to HTML");
                    pdftron.PDF.Convert.HTMLOutputOptions options = new pdftron.PDF.Convert.HTMLOutputOptions();
                    pdftron.PDF.Convert.ToHtml(doc, outputPath , options);
                    Console.WriteLine("Wrote " + outputPath);
            catch (PDFNetException e)

I get the following Error: Runtime Error! R6025 -pure virtual function call
only a part of the HTML is converted and no images/css are generated.
when i comment "options.SetReflow(true);" pdftron works as expected with no errors.
I am using win 10 with latest visual studio 2015 and pdftron.

Hi Currently the reflow feature is not available, though I’ll look into why there was a linking error, instead of an exception explaining it is not available.

It would be best if you explained what kind of output you are looking for? Is there something wrong with the default (non-reflow) html output? Are you looking specifically for reflow? If so, are images important for, since typically PDF to reflow HTML drops all images.

Hi and thanks for your answer
I need my app to read pdf documents(which might have 2or 3columns) in a mobile friendly manner. This way data will be shown on a single column:
pdf: column1 column2 column 3

what I want:

This way, the layout is a responsive web layout and not a fixed page.
