In active solution configuration drop down click new and call it something like x64
Now in the grid change platform to X64 (by default its Any CPU)
Now save you project
and the command is something like
devenv /build "x64" "d:\alarm\alarm.sln" /project "Alarm"
bold and underlined is the solution configuration name, hope you will figure out.
You can change active solution configuration if you like but at least create a new one for x64 platform
