For some older projects without solution files, you have to use makefile.vc files.

In a CMD shell, type:

"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat"
  or
"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars64.bat"

then

nmake /f makefile.vc [target]

--

Additionally, some projects need assembly code commented out for the x64 target
