How can I get several users reports on a centralized server /desktop?

In this case you should install Topalt Reports on all user computers and on the central server. Please make sure to enable automatic startup of the software.

Start the server application to enable reports over network (can be found on start menu). Then configure remote folders by specifying source, destination IP and folder path. The client software gets remove folders (that were specified on the server software) automatically once connected to the server.
