Hi Sivan,

You’re probably encountering the issue with having VS2013 Express installed along side other full versions of Visual Studio. Take a look at the solution here

Hi Nick,
thanks, probably it will be the solution as I have a full VS2010 installed similarly to others commenting that thread. I searched but had not found it.
Thanks again for the fast response!
