You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5 SP1

While installing SQL server 2012 RC0 on a Windows server 2008 R2 machine You might get an error telling you to install .Net 3.5 SP1.

Although I see it installed and did all the windows updates and .NET 4.0 is even installed.
So when you go to the download site and try to install it.

You get another error....

It seems that Windows server 2008 R2 comes pre-installed but not configured or enabled.

You just need to go to Sever Manager ---> Features--->Add a feature .  and enable it...

Or run that command... %windir%\system32\ocsetup.exe NetFx3  to configure it too.

Hope that helps someone...
