+# Install Visual Studio Express 2013
+
+If you don't alreadu have Visual Studio you can install the Microsoft "Visual Studio Express 2013 for Windows Desktop" available from http://www.visualstudio.com/en-us/products/visual-studio-express-vs.aspx which was used for this guide.
+
+Make sure you get "Visual Studio Express 2013 for Windows Desktop" specifically as there are several versions on that page.

+- Choose C:\Dev\CubicSDR for source.
+- Choose C:\Dev\CubicSDR\cmake_build (or any output folder of your choice)
+- Click Configure.
+- Choose "Visual Studio 12 2013 Win64" and Finish.
+- Note that both DirectSound and WASAPI are supported but WASAPI is enabled by default until some minor issues with DirectSound are resolved (YMMV).

+- Configure again, all should be good, then Generate.
+- Navigate to your output folder (i.e. C:\Dev\CubicSDR\cmake_build\) in explorer and open CubicSDR.sln.
