Start the installer and on the first screen of the Setup Wizard you will be presented with two options – one of them is “Yes, update the existing installation”. In this case you have an existing installation that has been recognised by the installer and you can upgrade this installation by selecting this option and proceeding with the installation without modifying any folder names or paths during the installation. If you select the other option – “No, install into a different directory” – you can create a new, separate installation of the software by modifying the folder names or paths presented to you during installation. Please note that this latter method is not suitable to “move” an existing installation from one location to the other. It will create a new, separate installation without overwriting the previous one.
