c# - Error reading word doc using Micorsoft.Office.Interop(Object library) via IIS 7

Question

Iam facing issue while reading the document when runnning code from IIS. It is not reading the document and throwirng an error "No document is opne when trying to save the activedocument.".

 m_word.Documents.Open(ref FileName,
                                ref missing, ref readOnly, ref missing, ref missing,
                                ref missing, ref missing, ref missing, ref missing,
                                ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);


 m_word.ActiveDocument.SaveAs2(ref FileName_rtf, ref FileFormat, ref missing1, ref missing1,
                    ref missing1, ref missing1, ref missing1, ref missing1,
                    ref missing1, ref missing1, ref missing1,
                    ref missing1, ref missing1, ref missing1, ref missing1, ref missing1, ref missing1);

m_word.ActiveDocument is giving error when running from IIS. It is working in visual studio debugging mode.

I also tried the below code:

 Document doc_open =  m_word.Documents.Open(ref FileName,
                                ref missing, ref readOnly, ref missing, ref missing,
                                ref missing, ref missing, ref missing, ref missing,
                                ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
            doc_open.Activate();

doc_open is retruning null and it throws object reference error in the second line. this works when code is in debugging mode. Error occurs when ran from IIS on development server where we have IIS 7 and MS offices too.
