First time Startup - Single or Multi-user Installation?

This is a part of the wizard that helps you with starting up the program for the first time.

If you are the only person who is going to use the program, you should install the Single-user version. You then install the database and program files on your computer, and only you will have access to the data.

For the Multi-user version, the database is installed on one of the connected computers or on a dedicated server. All the users then install the program files on their own computers, which retrieve information from the database.
