Upgrade vFabric License Server to the latest version to get the latest features and bug fixes.
From the Windows VM on which you are running vCenter Server, download the new version of the vFabric License Server installer program from the VMware Download Center and save it to your computer.
The installer program is called
vFabric_License_Server-.version.exe
On the same Windows VM on which you are running vCenter Server, double-click the vFabric License Server installer program from Windows Explorer to start the upgrade.
The installer program displays a message that this is an upgrade and asks if you want to continue; click Yes.
Continue clicking Next to accept the license agreement and finish the upgrade. The upgrade procedure keeps the same meta-data as when you first installed the License Server.
When the upgrade completes, restart vCenter Server for the license server changes to take effect.
