Can you help me check them? Be careful, some of them are virus.

@dunghnguyen,

I have observed the issue shared by you and suggest you to please first try using Aspose.Slides for .NET 17.7 on your end. If there is still an issue then please share the working sample code reproducing the issue on your end.

I’m using 17.7 and also shared sample above.

Presentation presentation = new Presentation(inputFile);
presentation.Save(outputFile, Aspose.Slides.Export.SaveFormat.Pdf);

Hi @Adnan.Ahmad,

Thank you for your time.
My code is only

try
{
Presentation presentation = new Presentation(inputFile);
presentation.Save(outputFile, Aspose.Slides.Export.SaveFormat.Pdf);
return 0;
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
return 1;
}

I forgot to mention that it happened in Windows Server 2008 R2 and CentOS 6.5.
I compiled an .exe, then I tried to execute it in CentOS under Wine (https://www.winehq.org/)

WINEARCH=win32 WINEDEBUG=-all wine test.exe
