Just recently, I've been twice prompted to update Opera 64 64-bit versions after I had already updated it to the current one via Opera's site. And Patch is showing Ccleaner as v. 5.62 and needing 5.63, when Ccleaner itself is showing 5.63. A screenshot of Patch vs. Ccleaner is attached.
Piriform has auto updated CCleaner internally and quietly for all users to v5.63 because it has important security fixes. but this doesn't change the registry version to 5.63 so you have to update it again with Patch My PC.
You're right. The catch is that Patch doesn't update Ccleaner here. Hasn't for quite some time. Have to do it from Ccleaner site.
