I am trying to deploy my Windows Universal test App built in Visual Studio 2015 RC on a recently upgraded HP Windows 10 tablet.

But app fails to install. The same application is correctly installed on my Windows 10 Laptop.

Complete error :

Tried the fix from <https://support.microsoft.com/en-us/kb/910336>.
 Also checked the reference links in error but no helpful diagnosis for this error code is given. 

Earlier I was able to install test apps on Windows 8.1 version using same process. Can it be due to Windows 10 upgrade? Any ideas?
