title: "ruby.exe is not recognized as an internal or external command" in windows 7
body: <p>My os is windows 7 and I was about to connect my localhost MySQL database with the Heroku shared database, in one point of time, I got the error libmysql.dll file missing, so I searched and downloaded the dll file and saved it in ruby/bin directory. Again when I was about to connect, this time it shows the error ruby.exe is not recognized as an internal or external command this is how the error looks.    </p>
