The Sims Medieval - Registering the game on Origin/EA App

Windows 10 user here and original discs owner.

I followed your steps and while it did get the game in my EA App, it gave me an error that states: "The Sims Medieval cannot run. The installation is incomplete. Please reinstall and try again."

So the troubleshooting began. I reinstalled the game 3x, repaired 3x, uninstalled and reinstalled the EA app all with no luck. I contacted EA support and they had no additional advice other than sending me these two links:

https://help.ea.com/en/help/origin/origin/installing-your-game-disc-through-origin-with-a-new-account/

https://help.ea.com/en/help/ea/ea-app/game-download-install-load-troubleshoot/

So, I tried the first link since the game did appear in the EA app and I happened to notice there was no product key in the properties area like my other Sims games, even though it was entered on thesims3.com.

In order for the game to recognize my valid key, I had to install both the base game and the EP discs. My product key then appeared in the EA app.

I then had to uninstall the EP, reboot, uninstall the base game and reboot. I then re-installed the game via the EA app. 

In order for the game to launch for the first time I had to change the compatibility mode to Windows 7. The game then informed me it didn't recognize my graphics card. So I closed the game, and ran Graphics Rule Maker to have the game recognize my card. Then I removed the compatibility mode.

After completing all these steps, I am now able to run the game with no issues. I'm assuming if I get a new PC or upgrade from Windows 10 to 11 all I'll have to do is run the Graphics Rule Maker and install via the EA app.

Just posting this in case it could help someone else out, or if I need it again in the future.

@Claumondragas so sorry i missed this originally.  your best bet is to try the steps Mate54 gave in the original post.  your only other option would be to contact EA.

@mate54Thanks a lot, I was already confused about it, as of now it still is loading to register. I am unsure if my account on the website is the same as my EA account. I believe so, But it so old thhat I do not even remember if they are connected together.

Edit: Never mind, it is downloading right now. I am curious how it will work out

I wasnt able to get my game into Origin, I am receiving the following error: 

I am the only owner of the game ever, and nobody other than me had access to the CD-Key which up to this day I have on the back of the original manual of the game. How can I contact EA to fix my account?

@Rey_Hammer , did you register the code at the Sims 3 website?

update: yes, I must have registered a long time ago (didn’t even remember, but I saw an additional content code inside the CD box that asked for the registration so, I figured that I must have done in the past, so after some email filtering I found and was able to recover - it has been idk, 8 years? So yeah, don’t blame me for not remembering, but I was glad that it automatically converted the account into an EA Games apparently, at least I didn’t have to take any additional step to convert/migrate).

however I still wasn’t able to play… origin/EA Games, just doesn’t work… the game doesn’t open, not even black screen of “trying to open”… and it gives an error on the EA games application saying something happened on their end…

so if anyone is looking to play, and was in the same situation as me, I can tell upfront it is not worthy… cuz even with the serial key and the game on the origin/ea games app, it doesn’t work…

I even saw some scripts related with processor affinity, but my processor is a 10th gen (also tried on a 7th gen) which doesn’t have this fancy core stuff, so it should work without that, even though I tried using it… anyway, the error says it is something on EA games side…  don’t  have the print at the moment (EDIT: just added below), but it is a default error that shows up on a lot of videos and places related with EA Games… some people said it was cache, it is impossible, I just downloaded EA Games on a recently installed OS, there are no cache files laying around… so I figure it does make sense to be something broken on their end indeed… I already didn’t expect much from EA, but this is way worse than my expectations, cuz the game is actually available to be bought… I would have been furious if I had just bought it nowadays and it is packed with a mystery on how to fry your pc with shady stuff to run a AAA game…

EDIT: including the error message;

I followed the steps, restarted EA.  The game shows in my installed games, however, the PLAY icon is grayed out. Under the MANAGE icon, it says "Purchase Game", there is nothing in the download manager.

@trinityHate , have you tried contact EA Help Support? They can check and see if the game shows up in your game library.
