TTG CE3 Publisher requires Lightroom 3 or above. The Publisher requires templates generated with the Web Module.
The server-side component of Publisher requires PHP 5.2 or above. Publisher will not work on Windows servers, and the only server platform that we fully support are Linux hosts. If you are looking for hosting, we recommend Bluehost.
While not required, it is recommended to run Publisher with a TTG CE3 Pages installation. The installation instructions assume that this is your setup.
