MVC file reading in c#

hi,

am using mvc 4 application. and iam working in mail merge consept in my project. so i done the mail merge coding part in my project then its working in local system only. and i publish the application and hoste to server. i can not read the .doc file in that server side.

am using Mircosoft.Office.Interop.word.dll

this dll was not working in server.

See this my code :

Object oMissing = System.Reflection.Missing.Value;

Object oTemplatePath = "F:\\test_bk\\TestTemplate.doc";

//Object oTemplatePath = "D:\\TestTemplate.doc";

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

Document wordDoc = new Document();

wordDoc = wordApp.Documents.Add(ref oTemplatePath, ref oMissing, ref oMissing, ref oMissing);

Server: windows 2008 r2

see the below error

Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
