CCleaner Not Cleaning

I have run the very latest CC edition on two computers - I have just updated from FileHippo. On both I run Firefox and Opera. On both the cleaner does not clear the cookies even though the appropriate box is ticked for each.

Which versions of CCleaner & browsers & OS/Windows?

Have you ticked Adobe Flash Player under Multimedia?
