Windows 10: How can I watch my purchased movie on my LG smart TV?

I purchased a Lionsgate movie Gamer from the Microsoft Movies and TV store, but Lionsgate doesn't participate in the Movies Anywhere app. How can I watch my purchased movie on my LG smart TV?

Watch movies on LG TV

1. Yes I can watch these movies on my computer.
2. Yes I can watch movies from other sources, Hulu, Vudu and Amazon
It seems to be only from the Windows store. It's asking for a Silverlight plugin?
3. LG HD Smart TV, 42LN5700

 

PC to LG Smart TV

How can I connect laptop to LG Smart TV (wirelessly) to watch DVD or saved movies? I've followed instructions for the LG Smart Share and researched processes but none work. Windows 10 does not have things Smart Share says to look for. I was able to do
it a few months ago streaming HBO to go from laptop but can no longer find a correct process.

 

Watch movies on LG TV

I have an HP computer running windows 10 and I have purchased some movies from the windows store. The problem is that they will not play on my LG HDTV, I have tried connecting directly to the internet from the TV and play them from the windows store and
I have tried to stream them from my PC to the TV. When connecting from the PC over my wireless network it shows connecting to the TV then says "the device cannot play the media source". Is there a way to get my HDTV to display the movies from the Microsoft
store.
