I'm unable to install the latest version of `Boost`, i.e. `1.61`. What I did was to run "`bootstrap.bat`" from the boost root folder in `Windows 7` prompt command, but error message says:

> 
> Building Boost.Build engine The system cannot find the path specified.
> 
> 
> Failed to build Boost.Build engine. Please consult bootstrap.log for

Any help appreciated!
