Hi All,

Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.ApplicationClass' to interface type 'Microsoft.Office.Interop.Word._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00020970-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002

I am getting this exception at:

((Word._Application)WordApp).Quit();

please give me any suggestion to resolve it..

Thank you..

You should not be casting to _Application as it is not the same type as your application object.
