Antenna House currently offers the following product licenses. Please refer to the new licensing structure.

Note: Antenna House strictly prohibits the use of the evaluation version for development purposes. Software developers and system integrators must purchase a Standalone License to use as a development tool.

The following chart shows the licensing structure:



A Standalone license is required for running AH Formatter on an individual or standalone computer. One standalone license is required for each standalone computer on which you wish to install and run AH Formatter. AH Formatter may only be used on the computer where it is installed. This license does not allow AH Formatter to be used for other computers directly or indirectly, even if they have access to the computer where AH Formatter is installed.

Note: GUI, .Net, and COM interfaces are only available for the Windows version.

A Server License is required for running AH Formatter on a server computer. An unlimited number of individuals can use AH Formatter through an API running on the server.

One Server License may be installed to only one server computer. However, there is no limit to the number of client computers that can use XSL Formatter running on that server.

One Server License is required for one CPU. That is, 2 licenses are necessary for a dual CPU server machine.


A Server license does not allow you to put executable programs such as .EXE .DLL included in AH Formatter on a file server and does not allow clients to read and run the programs on client computers.
