You can have more computer licenses (CAL/EAL) than concurrent connections(DAL) for the database. In the peer-to-peer configiration the Host computer uses a DAL when you start Crate Pro. You may want to 'release' the DAL from your host computer so that another user can log into Crate Pro on a client.
In the Client-Server configuration (uses FileMaker Server), the server does not use a DAL, so the only thing you need to do is have one user close Crate Pro and FileMaker Pro and the DAL is now available for another client.
For versions 17xx and 6.4xxx and later: On the Host computer select to Log-Out / Keys icon, at the top of the screen (do not click on the red X as it'll close the entire program). The screen shown below will appear. Do not 'Close Crate Pro' or 'Quit FileMaker'. This allows the files to continue to be hosted but releases the DAL (concurrent connection)
For versions 6.2xxx and 6.3xxx: On the Host computer > in Crate Pro 6 go to Preferences > At the top of the window is an option to "make this computer function as a server'. Select it.
To take back the DAL for the host:
Builds 17xxx and 6.4xxx - A client need to be logged out of the database if there isn't a DAL available. If all DAL are in use, when you attempt to login on the Host you'll have a opportunity to send a message to the clients to " log out" Select to LOGIN again once the clients have disconnected
Builds prior to 6.4 - Select to quit Crate Pro and restart the program on the host
