title: CRM 2011: SDK Install Error
body: <p>I have this problem while trying to install the SDK for Visual Studio 2012.<br/>
  I have tried installing Windows Identity Foundation, but I get a message saying "this upgrade is not necessary". It is installed on Windows 7 by default isn't it?
  I am busy installing Visual Studio 2010 for use in the meantime.<br/>
  What can be done about this?<br/><br/>
