Cant install avast internet security

Hey, i recently installed avast internet security from the New Program Update link , after uninstalling Kaspersky,but I receive a message that the file I downloaded is old and its need to download latest setup followed by “GUI was not initialized succesfully”. I never installed an avast product so this is my first time.And when I check the version of the file I downloaded its states 7.0.1456.418 while the link should download 7.0.1474.
Any solution ? Thanks

Thanks for the reply. The problem is that everytime i download from that link i end up with avast internet security version 7.0.1456.418,so i cant uninstall or use the aswclear without having it installed first

Using http://files.avast.com/iavs5x/avast_internet_security_setup.exe as provided by essexboy results in AIS 7.0.1474.765 installer being downloaded for me.
