You select one of the following options to install during the setup:
Microsoft Windows 8 Development
Windows Phone 8.0 SDK
After the installation of Visual Studio 2013 Preview is finished, you install Microsoft Visual Studio 2012.
In this scenario, you cannot change where Visual Studio 2012 is installed.
This problem occurs because the Visual C++ v110 tool set, which includes the Visual C++ compiler and libraries, is installed to a default location during the installation of Visual Studio 2013. The user cannot configure this location.
To work around this problem, install Visual Studio 2012 before you install Visual Studio 2013 Preview.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
When you install Visual Studio 2012 after you install Visual Studio 2013 Preview, the Setup program detects that some components of the v110 tool set are already installed and does not let you configure the installation location for Visual Studio 2012.
If Visual Studio 2012 is installed before you install Visual Studio 2013 Preview, you can choose the installation location of Visual Studio 2012. This location includes the v110 tool set files. Then, when you install Visual Studio 2013 Preview, the Setup program discovers and uses the previously configured location of the v110 tool set.
