Nuance Central Licensing Tool
NCLS handles Developer and Page Based license-related queries and tasks and communicates with NCLT through TCP/IP ports for Page and time restricted Licensing schemes. It runs as a Windows service and Microsoft .NET Framework 4 is required for its proper operation. NCLS accepts remote connections and can be located in the datacenter or in the cloud.
NCLT is basically the user interface for the NCLS. It displays the product name and version and a list of the features included with the license. It has License type dropdown for enabling selection between OEM, Fixed Volume and Page Based license types.
By using NCLT, you have the option to obtain and activate the license on a machine with or without an internet connection. However, it is strongly recommended that your developer machine has internet access. To ensure that licenses can be transported from one machine to another, a regular validation is required against the Nuance Activation Server. In case you do not have internet access on the machine, this validation cannot be performed.
You can manage your licenses via the NCLT.
