Can I use an InstallShield license for InstallShield 2016 to activate a copy of InstallShield 2019, or a 2019 license to activate 2016? Trying to help my team get on a consistent version of the software.
And there is no way to upgrade a 2016 license to a 2019 license? I need to purchase a 2019 license in order to use 2019?What about the other way around? Can I activate 2016 with a 2019 license?
