Windows Defender cannot instal it

[Guest]

I tried several times to install Windows Defender and I got the following:

Windows Installer
The feature you are trying to use is on a network resource that is
unavailable.

Hello rocasan,

Whatever you do, (installing and updateting or unistalling) always as a
administratºr.
This is the key!
The installation as an admin is not enough.
You needed to login as an Adm!n!stratºr.

Can you gº to Windows Update, select Express (Get high-priority updates),
and apply all offered updªtes
http://update.microsoft.com


Once that is finished, can you verify the update installs? There are many
pre-requisite files which are needed from windows update and signature update
with windows defender will fail until you hªve these f!les.
