Sql Server 2012 Installation

I am trying to install SQL Server 2012 Developer edition and I get the error at the bottom.

My system: 64 bit Windows 7

Things I have done:

  I have downloaded a different ISO from the MSDN site twice and I still get the same error.

  I have trying the installer in Admin mode 

FYI Previously I was able to successfully install an instance of Sql 2012 but I need to uninstall it and reinstall.  After the uninstall, I have not been able to reinstall.  Any ideas would be great. 

Thanks
