Since 2017, Appeon is developing and distributing the new generation of InfoMaker software, with the latest version being InfoMaker 2019. Appeon can provide your organization with new licensing and support for InfoMaker, but it would be necessary to upgrade to the new version, which is now sold as an annual subscription per named user (developer).
An Appeon InfoMaker subscription will allow you to download and use any version of InfoMaker developed by Appeon. This includes InfoMaker versions 2017 and above.
Projects made in previous versions of InfoMaker should be compatible with InfoMaker 2017 or 2019.
