Hi

Cannot open that PPTX (ticket already open/solved on that file ?):

code:

var ppt_path = "path_to_ppt";
var ppt_out_path = "path_to_ppt_out";
Aspose.Slides.LoadOptions _loadOptions = new Aspose.Slides.LoadOptions()
{
    BlobManagementOptions = new BlobManagementOptions
    {
        PresentationLockingBehavior = PresentationLockingBehavior.KeepLocked,
        IsTemporaryFilesAllowed = true,
        MaxBlobsBytesInMemory = 100 * 1024 * 1024
    }
};
using (var stream = new FileStream(ppt_path, FileMode.Open))
{
    Aspose.Slides.Presentation pres = null;
    try
    {
        pres = new Aspose.Slides.Presentation(stream, _loadOptions);
        Aspose.Slides.Export.SaveFormat ppt_file_aspose_format = GetPresFormat(ppt_path);
        pres.Save(ppt_out_path, ppt_file_aspose_format);
        Console.WriteLine("ok");
    }
    catch (Exception ex)
    {
        Console.WriteLine("ko");
    }
}
