Productivity Power Tools 2015 can not be installed on the RC version of VS 2015.

NOTE:

This version is signed in a manner which is not supported by the RC version of Visual Studio 2015. It will only install on the RTM version. You can download the RTM version of Visual Studio 2015 here - the Visual Studio 2015 Community Edition and higher support the installation of Productivity Power Tools and other Visual Studio Extensions.
