Lets do one simple thing before weekend. Lets activate SCOM license. If you open SCOM console in Help > About section you can notice that this version is Evaluation copy. Evaluation copy can work 6 months.
To find your license key, you will need to go to Microsoft Licensing Service Center and under downloads for System Center copy you license key.
To activate license you will need to enter it using PowerShell command Set-SCOMLicense. To do it, open PowerShell console in Administrator mode, and enter commands written below. You may need to restart your computer. Last command will show you license status. As you can see it still Evaluation license. It is entered in registry and it takes restart to load it
import-module OperationsManager Set-SCOMLicense -ProductId "<yourlicensekey>“ Get-SCOMManagementGroup | ft skuforlicense, version, timeofexpiration -a
After restart if you enter this command again you will get activated license and also Retail text in console Help > About
