Another reviewer mentioned that the install CD doesn't work. The problem was actually a glitch with install shield and on some machines the REG entry describing the location of VC++ wizards is missing so the path is invalid and install shield reports your out of space in the destination folder(bla bla bla). But if you have the technical ability to copy the INCLUDE and LIB directories to your hard drive and add them to VC++ directories under options, and copy the wizard (AWX) files to the appropriate directory, you'll be ok - and if that's too difficult, you probably shouldn't be messing with the windows shell anyway.
This is of course detailed on Scott Seely's web page and he provides and email address for you to contact him with any questions. I did in fact email when I got stuck building an extension that was not backed by a directory structure and streamed IO through a java app to provide virtual remote access to a server through explorer; he responded quickly and was very helpful.
