XAML editor failes, Package failed updates, dependency or conflict validation.Windows cannot install package App

Question

Hi,
I have just installed Visual Studio Express 2013 update on Windows 8.1 OS, and started a new Windows Phone App project. When I'm opening a new XAML editor window, it fails with the following error message:
System.Exception
Package failed updates, dependency or conflict validation.
Windows cannot install package App.af631a335.af069.a4bf5.a81c7.af4c34f85cb29 because this package depends on another package that could not be found. This package requires
minimum version 0.0.0.0 of framework Microsoft.VCLibs.120.00.Debug published by any publisher to install. Provide the framework along with this package.

Hello amanojkumar24,
I see a related error thread from here:
https://social.msdn.microsoft.com/Forums/windowsapps/en-US/b6a66a5a-e3b4-4f1a-848e-c1a6b7668b31/desgin-mode-breaks-down-during-windows-store-application-windows-8?forum=toolsforwinapps
As you've already repaired Visual Studio but Visual Studio still reports the error for you, we need to look into the error info:
This package requires minimum version 0.0.0.0 of framework Microsoft.VCLibs.120.00.Debug published by any publisher to install.
So here we need this package "Microsoft.VCLibs.120.00.Debug"
Please do the following:
1. Check your installation that you have enabled VC++ components. If you haven't or if you are not sure of it, please check this blog:
http://blogs.msdn.com/b/vcblog/archive/2014/08/01/c-runtime-for-sideloaded-windows-8-1-apps.aspx
Then you can download and install the package from
here.
2. You can also make sure you've registered and already have the license:

Someone fixed it by using this solution.
