I have the very same problem. I'm using Win 7. Ccleaner was updating fine for the first 3-4 months after upgrading to professional, and then kaputz. I did a re-install even after cleaning Ccleaner residue out of the registry and thought it would work, but it will update on a full install of the latest version of Ccleaner, but the updater spits out that message. "Oxf08: A redirect request will change a secure to a non-secure connection". Been doing this for over 6 months now. And yes, monitoring is turned on. Waste of money. It's ashamed, Ccleaner is a great piece of software. This problem just sours me a bit. Thanks for any help..My first time on this forum.
