执行GenerateProjectFiles.bat报错
GenerateProjectFiles ERROR: We couldn't find a valid installation of Visual Studio. This program requires Visual Studio 2015 or Visual Studio 2013 or Visual Studio 2012. Please check that you have Visual Studio installed, then verify that the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\14.0\InstallDir (or HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\14.0\InstallDir on 32-bit machines) registry value is set. Visual Studio configures this value when it is installed, and this program expects it to be set to the '\Common7\IDE\' sub-folder under a valid Visual Studio installation directory.
我已安装VS2015，并且尝试多次还是无法找到
