WGT Deploy and Installation

Hi everyone,
we truild to build a wgt package and install via HBrowser on a Samsung HTV with Tizen 3.0.
We created both author and distributor certificate but tv is not able to install wgt and it return a generic error.
We also defined a unique autogenerated application but it does not install either.

What can we do to create a web installation wgt package?

Many regards,
