If you have purchased an application that uses the Navigator Systems NX SQL Server, then you will have been issued with a Product Key starting with NSSQLV3.
Selecting "I have a product key" will then prompt you to enter that key.
If you have not purchased a server license and have no product key, then select "Install as a Trial". Selecting this option will automatically generate a product key that will allow the server to run for 30 days.
This key will be limited to two users and two sites. Your sales representative will be able to change this if required.
 
Please note that the trial key generation requires internet access and a valid email address. The key will NOT work until your email has been validated. Please see Trial request
