body: <p>When I trying to update Visual Studio 2012 to Update 3 I got this error: "<code>Failed to verify signature of payload: kb2707250</code>".</p>
  
  <p>I tried to reinstall VS, tried to update root certificates, I googled it for few days and I really don't know what I have to do to get this bloody Update 3.</p>
