InstallShield 2019 is a separate application form InstallShield 2018. You can upgrade to InstallShield 2019 by downloading the InstallShield 2019 installer from the Product and License Center and activating it using an InstallShield 2019 activation code.
You can have both InstallShield 2019 and InstallShield 2018 installed on your machine at the same time.
