CCleaner 5.56 Digital Signature Error

Recommended Posts

When trying to run the file ccsetup556.exe to install the newly released CCleaner V5.56, I'm getting a Firewall Alert about an invalid digital signature (see attached). Is this a correct situation or indicating a corrupted/malware file?

ccsetup556.exe downloaded from CCleaner.com has a valid SHA-1 and SHA-256 digital certificate on Windows 10.

What version of Windows are you using? I know when for instance on Windows XP it can't read the new digital certificates that are in software installers to help validate them.
