Can't Update CCleaner Browser

A pop-up appears when opening the browser saying that the browser can’t be updated.
I’ve tried downloading the installation file, but does not work.
I run Windows 10 Pro 64 bits.
How can I solve the problem?
Thanks you.

Same issue here, used direct download link, uninstalled and manually cleaned all AppData and ProgramData folders, reinstalled with admin privs, rebooted, cleaned again, manually cleaned in safe mode (to ensure nothing was missed) etc.
