Does Aspose.Slides support pptx presentations? I have error. "Aspose.Slides.UnsupportedFormatException : The file is ZIP archive. It can be Microsoft PowerPoint 2007 PPTX presentation."
But your site says: " Using Aspose.Slides for .NET, developers can easily open and save a large number of file formats. These include PowerPoint presentation, template and slideshow formats from 97 – 2003 and 2007 "
