Stuck with the error :Dx80072EE2 in SQL

I recently downloaded SQL Server 2012 release (SQL2012 RC0) free copy. During the installation I got the following error message (WindowsUpdate_80072EE2) at the time when the wizard was checking the latest updates. After this I can’t go ahead with the installation.
My Windows Update application shows the following messages in Control Panel.
Error:
SQL Server Setup could not search for updates through the Windows Update service. You can either check again or click Next to continue.
To troubleshoot issues with your Windows Update service, view the link below, ensure you have Internet or network access, and ensure your Windows Update service can find updates interactively through the Windows Update control panel.
