Can't get object to create

Hi everyone,

Here's a question about basics. I have dloaded and registered the TIDY DLL 
and attempted to simply run one of its demo pages, simple.asp.

No matter what I try to do, I only get the error,

"ActiveX component can't create object: 'TidyCOM.TidyObject'"
if I use 
Set objTidy = Server.CreateObject("TidyCOM.TidyObject")
        or
"Server object error 'ASP 0177 : 800401f3' 
Server.CreateObject Failed 
/info/webpublishtest/simple.asp, line 14 
Invalid ProgID. For additional information specific to this message please 
visit the Microsoft Online Support site located at: 
http://www.microsoft.com/contentredirect.asp."
if I use
Set objTidy = CreateObject("TidyCOM.TidyObject")

I'm at a loss on how to get Tidy to instantiate. Any advice out there?
