rails error (the System cannot find the path specified)

[Puria jahanbani]

When I type rails in the command line I get "The system cannot find the path specified." I've checked my environment variables and the directory is in fact there and when I type ruby -v I receive the version number as I should. Ruby and rails are both in the same directory as the path specified in my environment variables. Can someone help me figure out how to resolve this?

Thanks!

Actually I installed the package from http://railsinstaller.org/en. The rails.bat is in C:\RailsInstaller\Ruby2.2.0\bin and I've checked environment variables path and it exists. 
I've tried to install rails separately by "get install rails -V" and etc.. but It didn't work.

Its "gem install rails" , not get.

I'm assuming this is the first time you are installing ruby and rails. So just run this command without the -v option.

Oh sorry! Yeah that was gem not get, my mind mistake. That's right,
it's my first time to install ruby on rails. I've tried that command
in many ways, with -v without -v .. etc .. none of them worked! And
now I'm trying to install rails 4.2.3 , I hope it'll work. Thanks
anyway

Uninstall rails completely, gem uninstall rails

Then install it again. To install a certain version use the -v option and specify the version number within single quotes.

Below command works to install an older version. 

gem install rails --no-ri --no-rdoc --version=4.2.3
