Hi,

We are trying to convert word document to PDF and able to do the same on staging server with Microsoft office 2007 professional setup using

ExportAsFixedFormat

method from

Microsoft.Office.Interop.Word.Document 

from below code :

wordDocument.ExportAsFixedFormat(paramExportFilePath,
                            paramExportFormat, paramOpenAfterExport,
                            paramExportOptimizeFor, paramExportRange, paramStartPage,
                            paramEndPage, paramExportItem, paramIncludeDocProps,
                            paramKeepIRM, paramCreateBookmarks, paramDocStructureTags,
                            paramBitmapMissingFonts, paramUseISO19005_1,
                            ref paramMissing);

However it is not working on production server with Microsoft Office 2013 standard edition and gives below error upon running from IIS :

Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

I am not sure if this is due to office setup difference or we need to add any add-in ?

We have tried giving rights to DCOM config as well.

Please assist.


Thanks in advance.
