To resolve this problem, you need to repair the Windows SDK and tools for Windows 10, version 1511.
Steps to repair:

1. Start -> Control Panel
2. Under Programs choose “uninstall a program”.
3. This will present a dialog with all the applications installed on your Windows operating system. In the upper right hand corner type “kit”. This will filter the list of installed programs. One of the filtered applications will be “Windows Software Development Kit – Windows 10.0.14393.795”
4. Single click on Windows Software Development Kit – Windows 10.0.14393.795, and choose “change”.
5. This will present the Windows Software Development Kit setup dialog and there is an option to “repair”. Select repair and click Next.

This will repair the installation of your Windows SDK.

If you've reached this issue and you don't have the sdk at all you can get it here - you need the 10.0.14393.795 version.

These repair steps seem to fix the issue, closing!
