If you are running Windows Gateway version 20.0.0, you must complete a one‑time prerequisite before upgrading to version 21.0.0 or later. This step is required to address a permissions issue that can interfere with the upgrade if not resolved in advance.
Open PowerShell with Administrator privileges.
Run the following commands in the order shown:
sc.exe config OpsRampGateway obj= "LocalSystem" sc.exe stop OpsRampGateway sc.exe start OpsRampGatewayAfter the commands execute successfully, verify in the OpsRamp UI that the gateway reconnects and displays a Connected status.
Once the gateway is connected, proceed with the upgrade to Windows Gateway version 21.0.0 or later.
Completing these steps ensures the gateway has the required permissions for a smooth upgrade.
