A Standalone license is required for running XSL Formatter on an individual or standalone computer. One standalone license is required for each standalone computer on which you wish to install and run XSL Formatter.

XSL Formatter may only be used on the computer where it is installed. This license does not allow XSL Formatter to be used for other computers directly or indirectly, even if they have access to the computer where XSL Formatter is installed.

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 XSL Formatter on a file server and does not allow clients to read and run the programs on client computers.

The XSL Formatter Developer License is for developers who integrate the function of Antenna House XSL Formatter into an external application.
