I am trying to load a solution in Visual Studio 2013, but I get this message:

When I click OK, another error message appears:
An attempt to re-target the project has been canceled. the required assemblies WindowsBase ',' PresentationCore ',' PresentationFramework 'are not in the target structure.
I have the .NET Framework installed (I am running Windows 10) and I have already tried the .NET Framework recovery tool ( https://support.microsoft.com/en-us/kb/2698555 ).
