Enter license key in SCOM 2012
SCOM 2012 installs in evaluation mode as there is no way to enter the license key during install. You have to add the license key using powershell as described below when the installation has finished:
1. Start Operations Management Shell as Administrator
2. Run the following powershell cmdlet:
Set-ScomLicense -ProductId <your productkey>
3. Verify that the new licensekey has been set:
Get-SCOMManagementGroup | ft skuforlicense, version, timeofexpiration –a
