Licenses

Buy and manage your licenses in the portal:

License portal

Your LJLM license is tied to one computer at a time and each license includes a set of computer transfers so you can move your license whenever you upgrade or replace your machine. If you ever use up your included transfers, you can buy additional transfers at a small fraction of the license price - only when you actually need them. This keeps LJLM flexible and affordable: you always have access to the latest version, and you only pay for computer transfers when your hardware changes.
