Licensing Policy
Revision of September 26, 2026. About the transition to the subscription licensing model see the information notice of September 26, 2026.
QMB is always supplied in its full version. When a new SQL Server is registered in the program, a fully functional 30-day trial subscription is installed on it. After the trial period, a subscription must be purchased. If several SQL Servers are registered in the program, an active subscription is required for each of them. If several isolated instances of SQL Server are installed on one computer, one active subscription is enough to maintain all of them.
An activation key is used to activate the subscription. The key is sent by e-mail. At any given time an activation key can be activated on one SQL Server only. If needed, the subscription can be transferred to another SQL Server: deactivate the key and activate it on the other server. The number of deactivations is not limited. Both online and offline activation and deactivation are supported; offline activation and deactivation are used when the SQL Server has no Internet access.
Updates and Support
Support is provided by e-mail at support@qmbsql.com from 10:00 to 19:00 Moscow time while the subscription is active. Questions can also be asked in the built-in support chat. We usually reply within 24 hours.
