Bump 
A live ajax one would be amazingly brilliant, and would no doubt make it into the next official release, thus bring the developer of it untold fortunes.
Well, I know I’d appreciate it. 
Having exactly the same issue – getting a 404 on everything but the index and admin page.
Yep I am, but I’m only really trying to install at the moment, and integrate (with the plugin) after. I did set the correct prefix (wp_) in the config.php if that’s what you’re wondering.
Hi Sam, I’m actually not getting past install, it’s where I choose my initial (keymaster) login that I’m getting the error.
Even if I leave it blank (like it says to if I’m a new user) it still tells me that theres “no user found”.
Incidentally if I leave every field blank it still gives me the same error.
