I have my CCleaner set to notify me when there is an update but give me the option to install it or to wait for later. 6.21 popped up (I was running 6.20) and I let it update. When it restarted, CCleaner was asking for a Business license number.
I did not do any screen shots before, during, or after the update. Yesterday I uninstalled CCleaner, downloaded the Free Personal version and installed that on my laptop. So 6.21 is now the Free version that I have used for many years now.
