报错信息  >>>>>09:24:57 [错误] 打开/新建失败。详细错误信息：Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.ApplicationClass' to interface type 'Microsoft.Office.Interop.Excel._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D5-0000-0000-C000-000000000046}' failed due to the following error: 库没有注册。 (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)).     我就做了简单的创建打开，试了好多次都不行 WPS又可以正常被调用。求解！！！！
