Artlantis won't get installed?
When I launch the installer the message appear "Artlantis 5 is not installed on this machine, please install Artlantis 5."
That means that Artlantis 5 has never been installed before and you are using the updater instead of the Artlantis full installer.
Please download the full installer from www.artlantis.com / download
