If you are using the Virtuoso Embeddetech Target Development Toolkit, you will need to download and install Visual Studio before installing Virtuoso. Download and install the version of Visual Studio you will be using, either a Visual Studio 2013 or 2015 version.

Microsoft Visual Studio comes in several versions, including platform-specific Express versions (Express For Desktop, Express For Web, etc.) as well as Community, Professional, and Enterprise. Visual Studio Express and Community are free for student as well as non-Enterprise commercial organizations. If you are using a non-Professional Visual Studio license, we recommend using Visual Studio Community, however Virtuoso is also compatible with Visual Studio Express For Desktop. See below for more information on the Visual Studio Community License Terms:
