I am trying to open .docx file and convert to PDF using Interop.Word.Application. It works as console application but If I use the same in my web application it doesn't work. I tried to see the permissions on the folder. I gave 'Network Service' with full control, but still I get object reference not set at word.Documents.Open. Could you please let me know what could be the problem? I am stuck with this error. Please let me know. I appreciate any suggestions. Thank you.

    Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();

    object oMissing = System.Reflection.Missing.Value;

    word.Visible = false;
    word.ScreenUpdating = false;
    string fileName = @"c:\OUTPUT\test.docx");
    Document doc = word.Documents.Open(filename, ref oMissing,
            ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
            ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
            ref oMissing, ref oMissing, ref oMissing, ref oMissing);
        doc.Activate();
