A word of caution before installing this version…
CTPs are provided for testing and feedback purposes only. CTPs are unsupported, English-only releases. They are not subject to final validation and are not intended for use on production computers, or to create production code.
Installing a CTP release will place a computer in an unsupported state. For that reason, we recommend only installing CTP releases in a virtual machine, or on a computer that is available for reformatting.
Currently, Visual Studio “14” CTPs have known compatibility issues with previous releases of Visual Studio and should not be installed side-by-side on the same computer.
