OPAL licenses are issued for exactly the required number of users (user codes) respectively installations. Therefore no unused surplus licenses must be paid to use OPAL, as it happens with predefined license packages. The license fee depends on the selected OPAL product (e.g. OPAL Professional) and the required number of users (user codes) and OPAL client installations. Substantial discounts apply for multi-user and network installations.

Each installed OPAL license can be replaced and upgraded at any time to enable a changed number of users (user codes) or client installations. Likewise it is possible at any time to change the license from one OPAL product to another OPAL product (e.g. to upgrade from OPAL Solar to OPAL Professional). You can always continue to use an already installed OPAL system together with a new, changed or extended license without the need to re-install OPAL or to re-enter your data.

To obtain an OPAL license, you need the form OPAL License-Order, which is available for download. This document also contains the END USER LICENSE AGREEMENT FOR DOLPHIN'S DESIGN SOFTWARE.
