Sims 3 won't install from disc with codes - PC
I own the same discs (Sims 3 Starter Pack: base game, Late Night, High-end Loft Stuff) and the box they came in that I used to install the game the first time. I also have the same Origin account I had at the time of installation, as I couldn't download the game without it, even with all discs and codes on hand.
I already used the codes in the box to download the game to my Origin account on another computer, and it still works on that computer and on that account.
I'm using a new computer now, as I don't live under the same roof as the other computer anymore.
Origin still shows Sims 3 in my library, but I can't open it. I can't find any Sims 3 files on my computer anywhere either. Which makes sense, as I didn't originally install this game on this computer, so any data from the discs wouldn't be on it. So the logical thing to do here, since I no longer have access to the old computer that has the files/data, is re-install it all, right?
Problem is, I can't. It won't let me reuse the codes that I've already used for my own game that is connected to my own Origin account. It even says the code in Origin if I open the game properties window for Sims 3. The code in that window is the exact same code inside the box with the discs. I have everything I need to re-install the game right in front of me but it's just not working. NOTHING is working.
I'm beyond frustrated and ready to throw in the towel with this game. I've scoured the internet for WEEKS trying to find ANYTHING that would help. I've checked all forums, tried to do as replies said on posts that said answered, even looked at unanswered ones for potential suggestions. So please please PLEASE, if you'd like to help, please try to come up with an answer that's not anywhere else. Any potential real, working, up-to-date solutions for this particular issue would be much appreciated, and a sincere thank-you in advance to anyone and everyone willing to help!
UPDATE
I was able to get Sims 3 working! On Canada Day (July 1st), I was able to retrieve the missing files from the computer I last played the game on and move them to this computer via usb flash drive. It now runs perfectly! I don't know what's wrong with Origin on this computer. It's up to date, but necessary files were missing every single time I would attempt to re-install. It wasn't an issue with the computer itself as I can now play the game just fine on it. It might remain a mystery as to why Origin didn't install some things, but I'm just happy to have my game back! <3
