To fix this in VS2013 ultimate I had to follow the post http://rathodkrunal.blogspot.com/2011/11/visual-studio-2010-error-hresult-efail.html

Wherein it talks about simply cleaning out Visual Studio's ItemTemplateCache and running vs with the /setup flag one time.

In case the link breaks or is otherwise unavailable here's where the cache used to be for older VS:

You can delete the project cache at "Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplatesCache", then run "devenv /setup" to build the cache again to see if it helps.

You've been explicit about which versions of LS RC & the 2012 SDK you've installedc, but what version of the extensibility kit did you install? I know one was released for the Beta, I'm not sure if another one was issued specifically for LS V2 RC.
