I've been using CCleaner freeware for years. My operating system is Windows 10, and there's one device involved, a laptop.
Control Panel says I had an update, version 5.30, installed on 5/18/17. I guess it was a couple of days ago that I got notice that an update was available. I went to the table where features of freeware, and upgrades are listed. Scrolled down to "download" the freeware update, and pressed the download button. As it turns out, I can't update what is offered to me, 5.30, because I already have it. Another page was offering an upgrade. I scampered off to download and install the update to 5.30. And so, I am here, wondering what is going on.
Thank you for your attention to this,
