Visiting the Proteron website will take you to a page where you can download MaxMenus and LiteSwitch. Registration codes are provided for both. My assumption is that the two applications are no longer being developed (no update since 2007), but the developers were nice enough to provide download links and registration codes.

MaxMenus is an excellent application that I have been using for more years than I can recall. It has (and still is) one of the first applications I install on a new computer. My guess is that, eventually, it will not work on a future iteration of Mac OS X, and that will be a shame. I hope someone can pick up this application and resume development. If I were a developer, I would gladly take it on.
