Retrieving the COM class factory for component with CLSID {741F1E1B-0D59-4F59-A775-3E1B13721638} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using FiscPrinter = FiscPrnSys.IFiscPrnIface; 
using System.Runtime.InteropServices; 
public class Class1

    public void PrintBon() 
    { 
     FiscPrnSys.IFiscPrnIface FiscPrinter = new FiscPrnSys.FiscPrnIface();  (this  where the program is bringing this exemption) 
     FiscPrinter.Connect("COM2", 9600, data, parity, stopbit); 
     FiscPrinter.TestPrinter((short)48, "1,0,1", "HELLO");

    } 
    public void setTax(String pTax) 
    { 
     this.tax = pTax; 
    } 
} 

这个类被另一个类，这是所谓的

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using IncortexLibrary; 

class Program 
{ 
    static void Main(string[] args) 
    { 
     Class1 printer = new Class1(); 
     printer.PrintBon(); 
    } 
} 

输出：

这给headache.i已经在SYSTEM32注册文件.dll文件但它仍然给我带来麻烦。这意味着我在错误的程序中灌输程序，打印机显示为null.p租赁的帮助，因为我已经尝试通过网络来走，但我没有得到解决
