2.devenv.exe /resetskippkgs

3.devenv.exe /installvstemplates

Note that the above steps are unrelated and so checking if your issue has been resolved, after every step may help you save time on steps that were not required!

Please rename these 2 registry keys under the registry editor:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0
