Below is my code on click to button. If I will run project using localhost it will open word document very well but when I am going to host this project on IIS and try to open it from another machine by IP it will transfer my page to error message.
Microsoft.Office.Interop.Word.ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();
object file = "D:\\poForM.docx";
object objFalse = false;
object objTrue = true;
object missing = System.Reflection.Missing.Value;
object emptyData = string.Empty;
object readOnly = false;
object visible = true;
wordApp.Visible = true;
Microsoft.Office.Interop.Word.Document aDoc = wordApp.Documents.Open(ref file, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, visible, ref missing, ref missing, ref missing, ref missing);
aDoc.Activate();
