Opera browser in Selenium grid: Driver class not found

问题

I'm trying to setup an environment with Selenium grid to execute my Selenium test on a remote machine. The only browser I can`t get to work is Opera. I configured it the same as the other browsers. However when I start the node it shows a Driver class not found.

I`m Running windows 8.1 Enterprise 64 bit on my host computer

The node and the host are on windows 7 Enterprise 32 bit service pack 1

On the host opera is installed, the opera webdriver is in C:/GUI-Tests/Drivers/operadriver.exe, I tried the 32 bit webdriver and the 64 bit webdriver and I`m still getting the error:

13:30:37.169 INFO - Driver class not found: com.opera.core.systems.OperaDriver
13:30:37.169 INFO - Driver provider com.opera.core.systems.OperaDriver registration is skipped: Unable to create new instances on this machine.
13:30:37.178 INFO - Driver class not found: com.opera.core.systems.OperaDriver
13:30:37.178 INFO - Driver provider com.opera.core.systems.OperaDriver is not registered

If anyone knows something about this problem please help me.

Extra information about my environment

Starting the hub:

Answering my own question because I discovered the answer, and I`m hoping to help everyone that googles on this question :)

Well it turns out opera driver is a legacy driver, you won't need it.

You do need the Opera browser and operachromiumdriver. In c# define your capabilities as:

capabilities = new DesiredCapabilities();
capabilities.SetCapability(CapabilityType.BrowserName, "operablink");
capabilities.Platform = new Platform(PlatformType.Windows);
_webDriver = new RemoteWebDriver(_gridServerUri, capabilities);

On your node:

{
  "capabilities":
  [
    {
      "browserName": "operablink",
      "platform": "WINDOWS",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    }
  ],
  "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
  "maxSession": 1,
  "port": 5555,
  "register": true,
  "registerCycle": 5000,
  "hub": "http://localhost:4444",
  "nodeStatusCheckTimeout": 5000,
  "nodePolling": 5000,
  "role": "node",
  "unregisterIfStillDownAfter": 60000,
  "downPollingLimit": 2,
  "debug": false,
  "servlets" : [],
  "withoutServlets": [],
  "custom": {}
}

I hope this will be useful to someone at least it was useful to me.

Note:

operachromiumdriver is in my path variable
my node and hub are running Windows 7
