I'd like to validate both .NET framework 4.0 and 4.5 should be installed at server before proceeding a installation. Hence I used the following snippet, but I don't know about 4.5 validattion, which was not listed in the link Reference

<PropertyRef Id="NETFRAMEWORK40FULL"/>
    <Condition Message='This setup requires Microsoft .NET Framework 4.0 Full package or greater needs to be installed for this installation to continue.'>
      <![CDATA[Installed OR NETFRAMEWORK40FULL]]>
    </Condition>

The NETFRAMEWORK45 property can be used the same as the NETFRAMEWORK40FULL. Note there is no "client" or "full" framework for The .NET Framework v4.5. There is just one. So the following code should do what you want:

<PropertyRef Id="NETFRAMEWORK40FULL"/>
<PropertyRef Id="NETFRAMEWORK45"/>

<Condition Message='This setup requires Microsoft .NET Framework 4.0 Full package or greater needs to be installed for this installation to continue.'>
  <![CDATA[Installed OR NETFRAMEWORK40FULL]]>
</Condition>
<Condition Message='This setup requires Microsoft .NET Framework 4.5 package or greater needs to be installed for this installation to continue.'>
  <![CDATA[Installed OR NETFRAMEWORK45]]>
</Condition>

Note that .NET Framework v4.5 is an in place upgrade of .NET Framework 4.0 so checking for both could get you into a situation where you'll never satisfy both conditions. You might want to just check that .NET Framework v4.0 or .NET Framework v4.5 is installed. That condition would look more like:

<Condition Message='This setup requires Microsoft .NET Framework 4.0 Full or 4.5 package or greater needs to be installed for this installation to continue.'>
  <![CDATA[Installed OR NETFRAMEWORK40FULL OR NETFRAMEWORK45]]>
</Condition>
