Question

I'm trying to modify a predefined environment macros in Visual Studio 2015. Specifically this: VC_IncludePath

I can see it and its value, but I can not modify it. I don't see the option to do it.

Answer 1

You can edit this file:

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Cpp.Common.props

Answer 2

The value of this macro is automatically generated from the versions you have set in the property pages. Select Project, Properties, Configuration Properties, General and check that the Target Platform Version and Platform Toolset are correct for your installation.
