Before you can run OCAD 2018 you have to activate the software. OCAD 2018 can only be activated twice! The primary user is entitled to install and use the software on a second computer, if and insofar as this second computer is being used exclusively by the primary user (see License Terms).
While starting the software for the first time, the Activation Wizard will start automatically and guide you through the activation procedure.
If the error message Internal Error http.GetHttps.Url: .../testConnection.php appears while setting up connection... then a firewall may blocks the connection. Please use an alternative internet connection or the activation vie website in this case.
