System.ArgumentException

[Simon Sayes]

I'm using selenium chromedriver.exe in a C# visual studio 2010 project.

My only real line of code is this

IWebDriver driver = new ChromeDriver(@"C:\vs2010\selenium");

It simply starts an instance of chrome, I have tried identifying an manipulating elements which is fine, but I stripped the code to address an issue, which is in the output pane. 

"A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll"

I'm using Windows 7 32 bit up to date as of this post

Webdriver version 2.42.0.0 (27/05/2014)

This is normal to see in the output pane of Visual Studio if the library you're using catches an expected exception (which WebDriver may do in some cases). It is not, by itself, indicative of a problem. You'll need to provide further information.
