I\'m trying to use IsWindows7SP1OrGreater function, declared in VersionHelpers.h header. And I get:
\'VersionHelpers.h\': No such file or directory
In order to use the version helpers macros, you need to be targetting the v120 platform toolset this ships with VS 2013. If you create a an empty project in VS 2013 then you will find that an include of VersionHelpers.h works fine.
If you are targetting v120 then I guess something else is misconfigured in your project. Start with a brand new project and convince yourself that #include works as expected. Then try to find out what's different between your troublesome project, and the plain vanilla project that works.
