Hi, diff versions of Visual Studio may have diff installation path. So here mine in proper order: VCINSTALLDIR=C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\ LINKCMD64=%VCINSTALLDIR%\bin\x86_amd64\link.exe WindowsSdkDir=C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\ P.S.: I use: Win 8 Pro 64 bit, AMD Cpu, Visual Studio 2012 Express for Desktop.
