};
using (var stream = new FileStream(ppt_path, FileMode.Open))
{
    Aspose.Slides.Presentation pres = null;
    try
    {
        pres = new Aspose.Slides.Presentation(stream, _loadOptions);
        pres.Save(ppt_out, Aspose.Slides.Export.SaveFormat.Pptx);
        WriteLog("ok", LogType.info);

@pcaillol,
I used the following code lines:

var presentation = new Presentation("_save_corrupted_2.pptx");
presentation.Save("output.pptx", SaveFormat.Pptx);

It works fine.
