Unisphere Host Agent Setup Error cumulative update

Hello experts,
I downloaded the latest release of the Unisphere Agent I could find "UnisphereHostAgent-Win-32-x86-en_US-1.3.0.1.0015-1". When trying to install into Hyper-V 2012 R2 I get an error informing of the requirement for Feb 2013 updates to Windows 8 and Windows server 2012. Help me please !
Thanks !

Unisphere Host Agent requires that the February 2013 Windows 8 and Windows Server 2012 cumulative update or later be installed before proceeding.
Setup cannot continue.
First Run Windows Update and then install Unisphere Host Agent.
OK
