That's a Warning, not an Error. Note it says "2 Warnings" at the top of the window. An error will stop you from being able to compile your code into a dll, a warning will just let you know that something might not work after you compile. 

You can ignore that warning. That warning is saying that you're project is being built for any CPU, and the dll you referenced is only built for 64 bit CPUs. In fact I've changed my project to 64 bit CPU only under the configuration manager and then had issues with the debugger, so I just leave it alone.
