Since C/Side has gone forever, when installing Business Central on Premises you might wonder how to import or upload a license (flf) file into the service tier.
Well the solution is very simple.
First open the Business Central Administration Shell:
Then use the command: Import-NAVServerLicense:
More information is available here:
After importing a new license, restart all Business Central Server instances to activate the license for client users.
In case you try the above and you are still unable to login to Business Central due to a permission error, you might have to run the following SQL script on the Business Central database, using SQL Management Studio:
TRUNCATE TABLE “User Personalization”;
TRUNCATE TABLE “User Property”;
TRUNCATE TABLE “Access Control”;
TRUNCATE TABLE “User”;
This clears all users from the database. Then after running this script, restart the service tier and logon again. Your user should then be added as a SUPER user to the database and the logon error goes away…
TIP: Never run this script on a production database, because it removes all users and personalizations!
