This is the exact same error I get. I have completely deleted Ccleaner and tried to re-install it, but still doesn't work.
I also tried to delete the open processes of Cclaner in task manager, but no matter what I try I get that same error you get.
I hope this is resolved soon. I tried finding an older version of Ccleaner but no luck. Not to mention the fact that Ccleaner will try to update itself even if I find an older version.
