The first PC (XP SP3, P4.1GB) the installation stopped after Registrierunbg and enter the product code. When repeated login reproducible termination with "server not running" - Although the Internet worked. When download only a "dashboard" has been installed, which should be installed by other "apps" for download. This was ebenfallsn maybe possible because the login was not accepted.
I have used the scanner from Avira for years and recommended acquaintances - after this experience, I'll look around for alternatives.
