Can't install the Sims 3 (Discs) without Origin, but Origin no longer exists?
Hello, I am new here and am struggling to install my Sims 3 discs.
I haven't played for a good 12+ years but have kept them. I did used to play on origin but have only gotten back into the sims this year on the EA app. (Mainly playing Sims 4 that I brought in the online store). I'm not very tech smart and maybe these discs are now outdated and unusable, but I thought if I just put the disc into a external drive it would start up and I would be able to install and play. I own the base game of TS3 and a lot expansion/game packs (13 or so). I haven't tried to install any of those as I can't manage to get past the base game installation.
In the disc case, I have kept the 20 digit serial number/booklets and all of these games I brought 10+ years ago from the store. (No receipts but they would've be connected to my origin account)
Now onto what's happening. I've put the disc into the drive and it begins its automatic start up/set up, tells me to install origin, I install origin then origin asks me to install EA app, I "install" but it just takes me back to my homepage on the EA app and nothing else is prompted. I search sims 3 on the EA app and it wants me to purchase it for $30. I would attach more screen shots but I'm not quite sure how to do that. My current laptop is a MSi GL65 Leopard 10SCXR and I think I have Windows 10 installed but I'm not sure how to check, I'm sorry.
Can anyone advise what to do? Is there any way to install the base game and all my expansion packs? I tried to look for answers online but I'm hoping maybe someone here could tell me in laymen terms as I wasn't understanding what I was reading.
Thanks a lot for your patience in reading this, I do really appreciate any advice.
