The Chilkat .NET DLL is not an ActiveX, and does not need to be registered.
It should be located in the same directory as your .NET application's EXE.
(There are other ways for .NET applications to locate DLLs.) For ASP.NET applications,
the Chilkat .NET DLL (ChilkatDotNet.dll) should be placed in the "bin" subdirectory
relative to the application's root.
