Greetings, Backya -
A license is valid for any supported version, it is not tied to a specific version.
When I log in to appeon.com and navigate to the User Center, then Downloads, this is what I see (I've expanded the list of releases included in the PowerBuilder/Information installer):
When you run the installer you should be able to select the version/release you wish to install from the choices listed.
HTH
Best regards, John
