SQL Engine and Replication Licensing
c-tree is provided with an initial license that allows:
•	unlimited ISAM server features
•	limited SQL server features
•	no data replication features
The SQL Engine works for three hours from the c-tree startup and allows a maximum of 4 concurrent connections. 
In order to unlock the SQL server and take advantage of SQL features without limitations, you need to purchase a license. 
The same is applicable to the enablement of data replication features.
Contact your Veryant representative to purchase a license. You will be provided with a file named ctsrvr########.lic . In order to install the license
1.	stop the c-tree service if it’s running
2.	replace ctsrvr########.lic in the c-tree installation folder with the new one
3.	(re)start the c-tree service
