from install setup file here upgrade for Visual Studio 2012

Answer 5

I Found The Problem, vs 2012 doesn't support it(see update section of this answer)

From Here said:

Unlike Razor V2 runtime and design time, VS2013 did not GAC these binaries. Instead, the binaries are installed in the project bin folder when corresponding NuGet package is installed, and in “%ProgramFiles (x86)%\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\Web\Razor\v3.0” to support design time.

So we don't have these dlls in above path when upgrade to mvc5 /razor 3
