Cannot install new version of SafeZone

Avast Secure Browser Avast Secure Browser for Windows

Every time I open SafeZone I get the message “A new version of SafeZone browser is ready to be installed. Do you want to install the update now?”
If I click yes, the next time the same popup appears.
The version I am using is 1.51 running on a computer with Windows 7.
Is there a way to install the latest version?
