VS 2013 Cordova CTP 3.1: Windows-AnyCPU fails to install with Error : DEP0730

I have upgraded to VS2013 Cordova CTP3.1 and now cannot install the app to Windows-AnyCPU.

The Cordova app builds successfully but then fails to deploy reporting the following error :-

Error   13  Error : DEP0730 : Registration of the application failed because no Developer License is installed on the target machine. Package Microsoft.WinJS.1.0_1.0.9866.0_neutral__8wekyb3d8bbwe with Windows Store origin cannot be sideloaded or installed using developer mode option. (0x80073cff)   

The app successfully builds and deploys to Windows Phone 8, Windows Phone (Universal), Android and iOS.

I do have a valid development Licence until September this year and a C++ Windows App Store project successfully built, installed and ran on the PC.

Can anyone please help.

Are you running this on Window10 Preview machine? There is a known issue with trying to build a Cordova app for Windows-AnyCPU on Windows10 Preview OS, as explained here
