I have created a windows service that repetitively updates the same excel file. While running the Windows Service, I am receiving the following Error:

Error Message Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

This error is thrown at the following line of code:

ExcelApp =  new Microsoft.Office.Interop.Excel.Application();

Is there a work-around for this ?

I followed the steps mentioned in the following SO link but that didn't helped me overcome these error. I tried solution from few other questions as well and none of them worked for me.
