Convert PPT To PDF "Object reference not set to an instance of an object."

Hello

I am experiencing some issues on converting PPT to PDF files with Aspose.Slides V4.3.0.0

here is the code

Aspose.Slides.Presentation presentation = new Aspose.Slides.Presentation(inputFilePath);
presentation.Save(outputFilePath, SaveFormat.Pdf);

I created only one slide in ppt file and write only one line with common font (arial)

but when i tred to save ppt file as pdf

"Object reference not set to an instance of an object." exception occurs

Current os is Windows7(x64)

I attach the source ppt file

Thanks

Dear HyoDong,

Thanks for your interest in Aspose.Slides.

I have worked with the presentation file shared by you and have successfully exported the presentation to PDF using Aspose.Slides for .NET 4.3.0. I am using the same Operting System as shared by you. Please feel free to share if you may have any further queries. For your kind reference, I have attached the generated PDF as well. For downloading Aspose.Slides for .NET 4.3.0, please visit this link.

Thanks and Regards,
