The installation of System Center Operations Manager (SCOM) 2016 does not ask you anywhere to enter a license key. Then when you run the Operations Console, you are shown a required task to Upgrade to full version. When you click on the link, it opens a website that is less than helpful.
In fact, when you open the Help – About, you get a nice screen that says the product is not licensed to anyone, and you are using an Eval copy.
All this is saying is that we have not yet entered a product key for SCOM. For reasons I have never quite understood, there is no way to enter the license key in the GUI; you have to enter it in the Operations Manager Shell (essentially the PowerShell for SCOM), and you have to do it directly from the Management Server.
The command is: Set-SCOMLicense -ProductID “XXXXX-XXXXX-XXXXX-XXXXX-XXXXX”.
Once you do this, the Upgrade Required notice will disappear (when you restart the Management Console), and your product version in the About section will now appear as Retail.
Note: If you have any problems getting this to work with the Shell, try running the Operations Manager Shell as Administrator.
