COM Class Factory Error - c#-4.0

Question

I tried in console application it is showing Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
This is the error. How to solve this:
static void Main(string[] args)
{
StringBuilder query = new StringBuilder();
query.Append("SELECT deptId ");
query.Append(",[deptabbr], [deptname ], [deptnameLocal] ");
query.Append(",[deptabbrLocal ]");
// , [UnitPrice], [UnitsInStock] ");
//query.Append(",[UnitsOnOrder], [ReorderLevel], [Discontinued] ");
query.Append("FROM [dbo].[mDepartment] ");
//query.Append("JOIN Categories ON Categories.CategoryID = Products.CategoryID ");
//query.Append("ORDER BY Categories.CategoryName ");
