A client of my company has a question regarding GuiXT licensing. If they buy a license key for the production system, will they also receive a free license for the quality/test system?

The license keys for additional systems (e.g. development, quality, test) are always included.

The license key itself is system-specific. When a client buys a license, he normally sends us the system ids that he needs, e.g. DM6, QM6, PM6, and we generate 3 separate license keys for him. If there are more systems needed later on, all further license keys are issued free of charge.

The only limit that a client should observe is that the total number of actual users does not exceed the user number for which the original purchase was made.
