Defender beta 2

[Guest]

I have this message when I try to install it :

"Error 1609. An error occured while applying security settings. User is not
a valid user or group. This could be a problem with the package, or a problem
connecting to a domain controller on the network. Check you network
connection and click Retry or Cancel".

What can I do?

What can I do?

Create an account named Administrator (member of the Administrators group)
Create a group named Users

Install Windows Defender beta 2 from your account (if it is a member of the
Administrator group)
