Selenium Web-driver and chrome WebDriver incompatibility

[GoogleCodeExporter]

Hello, I am quite new in ruby, and I researched a lot trying to fix my problem, 
but I did not find anything that could help my situtation. I am facing a 
problem for some days now...
This is the first problem that I am posting here, so instead of marking the 
question negatively, help me to understand how to provide a proper info.
I am using watir to develop a automated test scripts.. I am using 
Selenium-WebDriver 2.43.0 and the the chrome WebDriver version is 2.12 and the 
Chrome version is '38.0.2125.111 m'.
In the FF and IE the browser opens normally, but in the Chrome the browser does 
not open and I get the following error:
O sistema não pode encontrar o caminho especificado.
O sistema não pode encontrar o caminho especificado.

If I change the place of the chrome-WebDriver, I get a error saying to download 
the driver... so I have discarded this possibility

I tested all of the Chrome-WebDriver versions.. until the version 2.8 I get 
this error: 
C:/Ruby21/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.43.0/lib/selenium/webdri
‌​ver/remote/response.rb:52 in assrt_ok: chrome not reachable 
(Selenium::WebDriver::Error::WebDriverError). But if the chrome webDriver 
version is 2.9 or higher, I get: 
C:/Ruby21/lib/ruby/2.1.0/net/protocol.rb:158:in rescue in rbuf_fill: 
Net::ReadTimeout (Net::ReadTimeout). Any thoughts?
