HOW TO FIX: SIMS 4 INSTALLATION FROM DISC NOT WORKING!!!

So i've seen lots of people have this issue and i've been trying to get it to work for almost 4 hours now.

Sims 4, when i insert disc (disk one) and click autoplay or go find the setup.exe

I AM PROMPTED WITH THIS:

STEPS TO INSTALL SIMS 4:

1. DOWNLOAD ORIGIN

2. CREATE ACCOUNT/SIGN IN

3. INSTALL SIMS 4

--CONTINUE---

i've clicked continue and i've already installed origin

so my question is, why am i not able to install it?

HOW TO FIX:

1. YOU WILL HAVE TO UNINSTALL ORIGIN AND ONCE THAT IS DONE DISCONNECT YOUR INTERNET

2. RE INSERT THE DISC AND RE INSTALL ORIGIN

3. ONCE INSTALLED AND UPDATED CONNECT INTERNET AGAIN AND LOG IN

4. YOU WILL BE ABLE TO INSTALL SIMS 4.
