Tizen Developers

Hello! I have a SMART TV Samsung UE40SV6450 from 2015. A few years ago I installed a widget on it. At the same time I used Tizen Studio 4.1.1 which included TV Extensions-6.0. Now I want to install another widget. I installed Tizen Studio 4.1.1 and found that it comes with TV Extensions-7.0. I was unable to install the widget with Tizen Studio 4.1.1 and TV Extensions-7.0. I think it's a matter of the Extensions version. Tell me how can I install Tizen Studio 4.1.1 with TV Extensions-6.0
