Sims 4 Disc install won't launch

Are you getting an error message ?

Here's instructions how the installation through DVD should work: http://sims4.crinrict.com/en/2014/09/installing-from-dvd/

I read and followed all that but it refuses to recognise the DVD in the drive and keeps trying to download via the internet. When I disconnect the internet it stops the download. Why does this have to be so complicated?!!!

I tried unistalling origin and reinstalling but that didn't help either

Does your computer read the content of the disc ok if you right click on your drive icon and choose open ? Maybe it's scratched or something ? Is downloading not an option for you ?
