Hi John,

>From your description, do you mean the error will occur if you change the
running account of the service without chaning one line of your code.

If so I suspect this issue probably caused by an access failure when
creating the COM component.
You may check the file permission of your .NET class library to see if the
service account can access it (Read, Read&Execute).
You may also need check the permission of registry node for the COM
Component to make sure your service account can read from it.

If the problem persists, maybe you need need use Filemon and Regmon to get
a complete log of the File/Registry access for your service, it might be
helpful to narrow down the problem and see which file/node caused the
Access denied.

If you still have problem after trying these suggestions, please feel free
to reply this thread to let me know and provide more detail information.

Good Luck!
