Unable to set SlideSize property while using powerpoint interop

We are trying to convert PPT file to PDF using Powerpoint Office Interop. We are using ExportAsFixedFormat() to do the conversion as shown in the below code snippet:

        public static void ConvertPowerPointToPdf(string inputFile)
        {
            string outputFileName = @"C:\All format files\PPT2PDF.pdf";

            Microsoft.Office.Interop.PowerPoint.Application powerPointApp =
            new Microsoft.Office.Interop.PowerPoint.Application();
            Presentation presentation = null;
            Presentations presentations = null;
            try
            {
                presentations = powerPointApp.Presentations;
                presentation = presentations.Open(inputFile, MsoTriState.msoFalse, MsoTriState.msoFalse,
                MsoTriState.msoFalse);

                presentation.PageSetup.SlideSize = PpSlideSizeType.ppSlideSizeA4Paper; //It throws the exception here

                presentation.ExportAsFixedFormat(outputFileName, PpFixedFormatType.ppFixedFormatTypePDF,
                PpFixedFormatIntent.ppFixedFormatIntentPrint);
            }
            catch (Exception)
            {
                throw;
            }
        }

The above code works fine if we don't set the SlideSize property. The moment we try to set SlideSize property, the exception is thrown as "PageSetup (unknown member) : Failed." Screenshot of the error message is shown below:

enter image description here

The version of Microsoft.Office.Interop.PowerPoint is 15.0.0.0 and Microsoft Office 15.0 Object Library is used as the Office core library. My PC in Windows 8.1 and I am using Microsoft Office 2013. Since we need custom output format, we need to setup SlideSize property which is currently throwing exception.

The code you have is correct. I was able to recreate your error exactly with with the presentation being marked as 'Final'. Try adding:

presentation.Final = false;

Add it before you resize. Hope it helps. Good Luck.
