CCleaner Analysis says 14,140,338,696.531 MB to be removed. Is this an error?
unless you are the proud owner of a petabytes drive, I'd be thinking that is an error.
just in the internal calcs of the amount, not the programs functionality.
I'd reboot and re-analyse to double-check.
what CC version?
in the analyse is there one section that accounts for all that (wrong) figure?
