AVEVA Enterprise License Manager gets stuck while Activating a License

When activating a license online in the AVEVA Enterprise License Manager, the activation results in the following error:

Unable to communicate with the Activation Server.
Ensure you have internet connectivity or proceed with offline activation by changing the activation settings.

License Server Core Service goes into a STOPPING state and machine must be rebooted in order to recover

The AVEVA Enterprise License Server repeatedly goes into a "Stopping" state.  When this happens, a reboot is required to restore it to Running.  The following message appears in the OCMC logs:

LS Agent can't use the ServiceController API to control the LS. Time out has expired and the operation has not been completed. Stack Trace: at System.ServiceProcess.ServiceController.WaitForStatus(ServiceControllerStatus desiredStatus, TimeSpan timeout) at LicServer.WindowsService.TrackSELicServer.MonitorLicServer()

This tech note will explain how to regenerate the license server trusted storage files to resolve the issue.

Cannot Select Licenses for Activation in AVEVA License Manager

It is possible to encounter a situation where you are unable to select licenses to be activated in the AVEVA Enterprise License Manager. In these cases, it may be necessary to replace the database file to correct the issue.

This tech note provides instructions to replace the License Manager database file.

Using AVEVA License Server OFFLINE Activation

AVEVA Licenses require license activation, a process whereby the authenticity of the license is verified against license records via the AVEVA License Activation Server and the license is bound to the license server from which the activation was initiated.

License activation requires communication over the Internet with the AVEVA License Activation Server. That communication can be either direct over the Internet (Online Activation) or indirect through a proxy computer (Offline Activation).

This Tech Note describes the process of activating an AVEVA license using OFFLINE activation.

Ending AVEVA License Server Grace Period

Certain conditions can cause the AVEVA Enterprise License Server to enter a License Grace Period. The Grace Period allows the server and licenses to operate normally for fifteen days. Once the fifteen day period has expired, the License Server will no longer allow licenses to be acquired. Removing the Grace Period mode will allow the License Server to function normally again. This tech note will provide instructions for two methods that can be used to remove the Grace Period mode from a License Server.
