I bought a 2-yr subscription of CCleaner Premium Oct 2024. When I downloaded the files and installed them, it became CCleaner 7. This version was never mentioned and has an all-new look, which I find confusing. Even worse, whenever I use Custom Clean, it continually issues “Unable to Clean” on files selected to clean! I have two laptops Win11, and this happens on both. Why does my invoice say I bought CCleaner Premium, but I got CCleaner 7? Why does CCleaner 7 continually not clean files selected to clean?
Basically because those files are open, and so can’t be cleaned - it will get them next time (but may tell you about others that are then open).
The old CCleaner used to do it too - but it didn’t tell you about it, because telling people just confuses them.
Whoever is responsible for the new version isn’t yet experienced enough to realise that and so it now tells and confuses people.
If you prefer the older style CCleaner then for the download link(s) and roll back instructions click this: How to Roll Back from v7 to v6.39 and follow ALL of the instructions there. (If you don’t follow the instructions it will update itself to CCleaner7 again).
Hi Nukecad,
Thanks for replying to this irritating issue. I do prefer the older CCleaner version vs this new one for the reason you mention: it’s confusing and irritating. I’m having problems trying to find how it was so easy to find in the older version! So I’ll use your link to go back to it.
BTW, I’m not a computer troglodyte. I was a technical writer for both SW and HW for high-tech firms in Silicon Valley, including Seagate, working decades with engineers. In fact, I’ve used CCleaner since it was called Crap Cleaner. One of the favorite parts of writing procedures for SW was making instructions easy to understand–regardless of one’s IQ. Also, I was used by QA guys as the “dumb user” so I could stumble onto bugs before the SW was released. Whoever revised CCleaner does not understand how people think nor understand stuff, as you said. They assume way too much!
The thing driving me crazy is how utterly complex and frustrating all high-tech devices are becoming. I bought a new laptop (HP OmniBook X) a month, which is so complicated to understand that it took nearly a week to set it up so that I could use it, and I’m still not finished! Way too many features that I utterly have no clue what they are nor can understand the descriptions–and I’m not a neophyte! (Same with my new cellphone–about 90% of what’s on it I don’t understand.) I hate Win11 for that reason. I want to go back to Win XP or Win 7! 
OK, enuff of my rant..
Thanks for your help.
