ASP error Server.CreateObject with new server IIS7/WS2008

Question

Getting an error when migrating an old ASP script to a new box. The old server was IIS6, Windows Server 2003. The new server is IIS7, Windows Server 2008. Here's the error:

Server object error 'ASP 0177 : 800401f3'
Server.CreateObject Failed
/img.asp, line 39
800401f3

The offending line is

set download = Server.CreateObject("csFileDownload.Binfile")

Answer 1

Is the csFileDownload.Binfile component installed and registered on the server?

Answer 2

There's two things that jump out right away:

1. You may not have enabled ASP in IIS7 http://forums.iis.net/t/1007530.aspx
2. You need to register the COM object that contains the csFileDownload.Binfile class by calling regsvr32 path to dll from the command line.
