Work with the Grace Period

The Grace Period is a twenty-four hour period in which InTouch can continue to run with the last good license's capabilities after certain conditions have occurred. Both WindowMaker and WindowViewer can enter the Grace Period. At the end of the Grace Period InTouch will terminate if a valid license is not reacquired within the allotted time.

The Grace Period will be triggered by the following scenarios. If valid license is not reacquired within twenty-four hours, WindowMaker or WindowViewer will terminate.

When WindowMaker or WindowViewer enters the Grace Period, you will be prompted with the following dialog:

You have the options to be reminded again, to retry to acquire the license, or to exit the application.

Scenario 1: Consumed License is Lost

WindowMaker or WindowViewer will go in to Grace Period if it consumes a valid license from the License Server and the license is deactivated while the product is still running.

To exit the Grace Period and resume normal operation, activate a valid license on the License Server. When the license is consumed, WindowMaker or WindowViewer will exit the Grace Period and normal operation will resume.

Scenario 2: License Expired

WindowMaker or WindowViewer will go in to Grace Period if it consumes a valid license from the License Server and the license expires. To exit the Grace Period and resume normal operation, activate a valid license on the License Server.

If WindowMaker or WindowViewer fails to acquire the license, the first dialog will appear again.

Scenario 3: License is Downgraded

AVEVA Enterprise License Manager is a server-based licensing system, which means that licenses need to be renewed periodically. If a WindowMaker or WindowViewer license is downgraded during this renewal to one of lesser capability, it will enter the Grace Period. See Manage consumption of a different license after startup for a detailed description of downgrade scenarios.

To exit the Grace Period and resume normal operation, retry to acquire the last good license or a better license.

Important: The functionality enabled by your last good license will persist in Grace Period mode.

In all of the above scenarios, if you select the option to retry to acquire the license and an appropriate license is successfully acquired, you will see the message that the license has been acquired successfully.

If InTouch fails to acquire the license, the first dialog will appear again.

Note: Configuring the ViewLicenseRetryCount key in the InTouch.ini file, will instruct WindowViewer to continue to attempt acquiring a license in the background for the number of times specified in the parameter. If a license is acquired, the dialog box will close and WindowViewer will be launched.
