Retrieving the COM class factory for component with CLSID {XXXX} failed due to the following error: 80040154

by

I developed a Windows service using C#.NET to generate PDF report. To generate PDF file I am using a third party dll. The application is running in my Windows XP platform. When I deployed the service in Windows Server 2008 64 bit version, I got this error:

Retrieving the COM class factory for
component with CLSID
{46521B1F-0A5B-4871-A4C2-FD5C9276F4C6}
failed due to the following error:
80040154.

I registered the DLL using the regsvr32 command. I able to see this CLSID in the registry. But the problem persists.

What could be the problem?
