Windows Live Mail Win 10 cannot get it to work

I was looking for  WLM  on this computer,  it what I always use for email, I just had installed Win 10 last week

When I clicked on the installer a  pop up appeared saying it needed repaired, I clicked on that and it appeared it was repairing it viewing the green line like you see with updates. After that the Windows Live starting  window came up then disappeared, I could not find WLM again, when I clicked on the mail icon in the menu bar I got this

 Windows essentials is in program files, do I need to uninstall this? then reinstall?

Why didn't this just work, doesn't MS test these problems before they offer upgrades?

I don't consider Win 10 free as it taking too much of my time.

Thanks in advance
