Creating Instance Failed Error (8007045a)

Hello,

My .NET 2.0 Web Service application fails when trying to connect to a
COM application. It throws the following error:

"System.IO.FileLoadException: Creating an instance of the COM
component with CLSID {1D56AF9F-8BAB-4BB5-A000-D97055AD50E6} from the
IClassFactory failed due to the following error: 8007045a."

It used to work correctly in a PC with WinXP and Visual Studio 2005
installed. But in my actual system with Win XP Embedded and without
Visual Studio it fails.

Can somebody help me please?

Thank you very much,
Nearvi
