Cannot Create ActiveX Component -- in a service

I'm having an issue concering the CreateObject method and a service I've been developing. I've written a DLL that executes the statement:

CreateObject("CognosImpromptu.Application")

When I reference this DLL through a regular app this statement executes easily and the rest of the function completes. However when I reference this DLL from a service running under a domain account I get the error "Cannot create ActiveX component." The domain account has been given Full Controll permissions over the executable (ImpAdmin.exe). What could be the problem here?

Thank you in advance for any help.
