Licensing > Concept

Licensing in Common Vision Blox relies on two items:

•the Common Vision Blox serial number and

•the (tool-related) Magic Number.

Together, those two allow for a flexible and modular licensing concept that fits the modular nature of Common Vision Blox.

•Starting with Common Vision Blox 11.x, Common Vision Blox licenses will by default shiped with a WIBU CodeMeter USB dongle.
The hitherto used SafeNet Sentinel SuperPro will continue to be available upon request for duplicating existing installations based on older versions of Common Vision Blox, but will only support the Win32 version of Common Vision Blox (whereas the CodeMeter dongle will work for all supported platforms).

•The underlying architecture for querying license information from the dongle or other license providers has been changed to use asynchronous mechanisms in order to eliminate the timing differences between the different license providers.
In other words: the dongle licenses will not react any slower than e.g. Node Locked Licenses and an individual license query will typically take less than 1 millisecond.

•It is possible to use several different licenses simultaneously.
If, for example, you own a dongle for which you have the Magic Number for Minos, and another one for which you have the Magic Number for CVC Blob you may simply plug in both dongles, add both Magic Numbers to the License.ini file and use both tools in one application.
Please note that as a consequence the functions GetSerialNumber and GetLicenseInfo are no deprecated as they cannot be adapted to this scenario.
They have been replaced by UpdateLicenses, GetLicenseCount and GetLicenseInfoEx (see the reference documentation for the CVCImg.dll for details).

•Customers buying one of the new WIBU CodeMeter dongles with a Common Vision Blox License and simultaneously one or more Common Vision Blox tool Magic Numbers will no longer need to enter these Magic Numbers into the License.ini file because in this scenario STEMMER IMAGING will write them directly into the dongle.
This makes porting all the licenses from one PC to another significantly easier.

•In addition to the Common Vision Blox Serial Number and the Foundation Package Flag a license provider will now potentially report additional license properties:

oCommon Vision Blox Major version(s) for which the license is valid

oPlatform on which the license is valid

oExpiration date of the license (optional)

•The CVB License Manager can be used to display these new properties of Common Vision Blox Licenses.

•It is no longer necessary to specify the Magic Numbers for Common Vision Blox Serial Number 999 – the system already knows them.
Consequently, users activating a time-limited Trial License will no longer receive a *.lic file along with the activation key.
