CCleaner deleting file associations

continually deleting correct file associations reporting them as "unused",

when scanning Registry, 1st time problem still occurring after reinstall,

making registry cleaning portion unusable.

Can you give a bit more info slim?

Operating system used

Cleaner version.

Which reg association names ( a screenshot if you are okay with doing that) get broken after the reg clean.
