Installing SharePoint 2013: .Net 4.5 error

I faced the below error whilst installing SharePoint 2013 on Windows Server 2012, I did run pre-requisites tool before the installation.

I cross checked the features under the Server Manager for .NET framework 4.5, which was installed.

The issue turned out to be the versions of SharePoint and Windows. I was trying to install SharePoint RTM on Windows 2012 RC
