It's not possible to deprogram your remote, unless it is hooked up to the PC via a USB cable and then logged into your account on Logitech's server. What problem are you having with the remote?

Welcome to the forum - all Harmonys use the same software that you can download from the Products link here - and when you tell us what's wrong with the 550 we'll tell you how to put it right without "reprogramming".
