Help! Can't install Sims 2

How do I describe this issue? Well..when I digitally try to install Sims 2 through Origin it never fully loads all of the content leading to an error message when I try to run Sims 2 and update it. Sure...I have it working on an ancient laptop but it lags, etc. etc. I don't know if this is clear enough...maybe I need to take a video of what I'm talking about.
