From Layton Support
This page contains the Layton ServiceDesk license information and customer details. The version is displayed together with the Customer Name, Customer ID and License Key. It will also display the number of End Users and Analysts that you are licensed for.
Without a valid license key the system will operate in evaluation mode. If you are a registered customer you can use the Get License Key link to generate a product key from our web site. You will need to enter your Registered Company Name & ID details before clicking the Get License Key link as it will use these details to login to the customer support section of the Layton Technology website.
