Writing to an External Log File

I'm attempting to execute this example in your documentation:  http://docs.telerik.com/teststudio/advanced-topics/coded-samples/general/external-log-file#excel-file

I've included the reference to Microsoft Office Excel DLL.

Although there is a reference to a Text Log example, too, it calls for the inclusion of the ArtOfTest.Common.Design.  However, when I navigate to the referenced directory of "C:\Program Files (x86)\Telerik\Test Studio\Bin", the DLL is not present.

I've included a picture of the IDE with the Excel code.
