The Sims 3 cannot install, how to fix this?

I downloaded the Sims 3 on origin, and when I install it I input the country, and then it ends.

When I open the setup file in the folder, I get to accept the license agreement, and then it ends.

The reason why I reinstalled the game is because I had an issue that caused most of the buildings/lots in the town to disappear and one of my sims also disappeared along with all his belongings, so I could also use some help with that issue.

I have tried manually uninstalling and reinstalling the game (clearing the registry and everything), running origin as administrator, running the setup file as administrator, but it never works.
