I just followed the wiki a week ago and everything worked fine for me. Pay attention to the installation option questions when installing since you'll want context menus and path stuff added during the install(s). The wiki does a good job of explaining it in detail but in the event an updated installer changes and doesn't have the same options either use common sense (not click click click done) or keep notes on what options you did or didn't enable during your install process so you can ask detailed questions here if you have problems.
