加载所有扫描仪设备？

Question

嗨，我真的需要帮助 我键入此代码以将所有连接的扫描仪设备加载到acombobox 但它在Windows XP中的Windows 7中工作我得到了这个嘈杂的异常

由于以下错误，检索CLSID为{00020819-0000-0000-C000-000000000046}的组件的COM类工厂失败：80040154。

这是我的代码

public static void LoadScanners(ComboBox c)
   {
       MC.enableWIA();
       string deviceName = "";
       c.Items.Clear();

       WIA.DeviceManager deviceManager = new WIA.DeviceManagerClass();
       // Loop through the list of devices and add the name to the combobox

       foreach (WIA.DeviceInfo info in deviceManager.DeviceInfos )
       {
           if (info.Type == WIA.WiaDeviceType.ScannerDeviceType)
           {
               foreach (WIA.Property p in info.Properties)
               {
                   if (p.Name == "Name")
                   {
                       deviceName = ((WIA.IProperty)p).get_Value().ToString();
                       c.Items.Add(deviceName);
                   }
               }
           }


       }
   }

此行发生异常

 WIA.DeviceManager deviceManager = new WIA.DeviceManagerClass();
