IPresentation presentation = Presentation.Open(@"D:\YUs\Test\pp2.ppt");
            presentation.ChartToImageConverter = new ChartToImageConverter();
            presentation.ChartToImageConverter.ScalingMode = Syncfusion.OfficeChart.ScalingMode.Best;

            PresentationToPdfConverterSettings settings = new PresentationToPdfConverterSettings();

            settings.ShowHiddenSlides = true;
            PdfDocument doc = PresentationToPdfConverter.Convert(presentation, settings);

Using the code above (which I copy pasted from the sample), I can convert PPTX to PDF.. but when I tried to convert PPT to PDF, it returns the error

Syncfusion.Compression.Zip.ZipException: Zip exception.Can't locate end of central directory record. Possible wrong file format or archive is corrupt. at Syncfusion.Compression.Zip.ZipArchive.Open(Stream stream, Boolean closeStream) at Syncfusion.Presentation.FileDataHolder.Open(Stream stream) at Syncfusion.Presentation.Presentation.SetArchieveItems(Stream stream) at Syncfusion.Presentation.Presentation.ParseDocument(Stream fileStream) at Syncfusion.Presentation.Presentation.OpenAsStream(Stream stream) at Syncfusion.Presentation.Presentation.Open(String fileName) at

Hi Abdul,
Thank you for your interest in Syncfusion product.
We have checked the details and Syncfusion Essential Presentation library only supports manipulating "PPTX" documents and this error message will be shown while you are using “ppt” documents (the file extension for PowerPoint 2003 and earlier versions) in our presentation library.
We would like to inform you that we have logged “Need support for using PPT documents in Essential Presentation library” as a feature request in our database. We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. Please log on to our support website to check for further updates:

Did this ever make it into the product?

I'm still receiving the same issue.
