I installed the XmlActiveX.msi app as an admin on my Windows 7 workstation, and it looks like the libraries registered properly, but when I run the sample code from the page below (verbatim), I'm getting the error, "ActiveX component can't create object: 'Chillkat.Rss'".
I'm pasting the code into a new text file (with the VBS extension).
The .msi probably did not have permission to update the registry to do the ActiveX registration. I would recommend instead downloading the .zip containing all the ActiveX DLL's from here:
Then register the DLL's manually. Make sure to follow the instructions carefully.
See this Chilkat blog post for more help in registering ActiveX DLL's: http://www.cknotes.com/?p=361
