There is a lack of permissions in the registry key HKU\S-1-5-20. The Network Service account must have full control and read permissions over that registry key.
This situation may be the result of applying a Plug and Play Group Policy object (GPO).
To resolve this issue, you can either disable the policy setting (Method A), or edit the permissions to provide the Licensing Service the required permissions (Method B).
Method A: Disable the Plug and Play Policy

Computer Configuration / Policies / Windows Settings /Security Settings / System Services /
If the Plug and Play service is configured through a Group Policy setting, you see it here with settings other than Not Defined. Additionally, you can see which Group Policy is applying this setting.
