How to keep COM object alive in .NET windows service?

I have created windows service which instantiates COM object in OnStart event of the service. While the service OnStart is in process, I can see the COM EXE in running processes (in task manager) but once the service is completely started, the COM instance gets destroyed. I googled on this in which I got an answer to implement STA thread process to instantiate COM object. But after implementing threading, I now get error as "Retrieving the COM class factory for component with CLSID {D66B3D9C-D465-46B8-BFB4-F63F04FB203C} failed due to the following error: 80080005."

Please help me out...

We found that the COM component we were using was expired. We brought the licensed copy and now it works fine even without threading. Apology for the trouble.
