“ruby.exe is not recognized as an internal or external command” in windows 7

Question

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.

Linux answer: ruby is not in your $PATH. I think it's %PATH% in Windows. — Reactormonk

You don't have the ruby.exe's path in your PATH variable.

In windows 7 you can set it by Start menu -> right click My computer -> last option on the left (I think it was advanced settings) -> Environment variables -> in system variables sub menu find Path double click it and add ; then the path to the bin folder of your ruby installation. This should fix it (you will need to restart all command prompts you have launched).
