Hi Viral,


I have observed the stack trace shared by you but in order to further investigate and resolve the issue, I may request you to please share the source presentation along with used code snippet. Please share the information related to Aspose.Slides for .NET version used along with platform information.

Many Thanks,

I will try to get that sample pdf. We are using following code snippet:



case “.pptx”:
Aspose.Slides.License pptxLicense = new Aspose.Slides.License();
pptxLicense.SetLicense(“Aspose.Total.lic”);

Aspose.Slides.Pptx.PresentationEx presentationEx = new Aspose.Slides.Pptx.PresentationEx(sourceFile);
presentationEx.Save(destinationFilePath, Aspose.Slides.Export.SaveFormat.Pdf);

retVal = destinationFilePath;

Hi Viral,


The code snippet that you have shared seems OK. I would suggest you to please try using Aspose.Slides for .NET 5.9.0 as well on your end. If the issue still persist then kindly share the source presentation with us that is throwing exception.

Many Thanks,
