I have deinstalled origin and the sims 3 via revo again, clean installed both and done your latest suggestions. But it didn't help, sadly.
When it comes to your question of how I did it with the disc;
I have installed the game with the disc, like two times. First it launched without a patch whatsoever, in-game it said I could update the game through the EA Download Manager so that was what I did. I closed the game and updated it.(it got updated to 1.67). And later when I have installed Origin to download all the rest of the addons, it launched once, funnily... it didn't even wanted to update the game o.O. But after closing the game it forced the game to get "repaired", so it could get updated to the newest version, but it got broke and stopped launching with that same error code. So I have deinstalled both again(Origin & Sims3)
Later I have installed it again with the disc, and the game didn't launch, not even react with any error. But it did launch after the patcher. I wanted to try it again with Origin, but it did something similar to before, but instead of launching it once, it wanted to "repair" it right away.
@Avareee I meant to ask another question but forgot to include it: Do you own any other Origin games, and if so, do they work on this computer? Please let me know what they are.
Yes I have Battlefield 3, which works seamless. I own some others aswell, but never tried them on this Computer.
EDIT: By the way doesn't the launcher "call" the TS3.exe anyway, when you press 'play'?
Also, when I just launch TS3.exe without opening Sims3Launcher.exe(in ProgramFiles(x86)\Origin Games) I have the same error.
So what kind of difference would that make, renaming them?
@Avareee If the launcher is somehow the problem, whether the launcher itself or the transition to or from it, then bypassing it entirely could help. I've always read that the launcher can't be bypassed on a 1.69 install. However, I wasn't sure that this was technically true: if Origin is trying to call the launcher but just blindly opens whatever is labled "Sims3Launcher.exe," then renaming TS3.exe to that might cause Origin to open the game directly instead of forcing you to go through the launcher. But like I said, I haven't tried it myself.
This is different than trying to open TS3.exe directly: doing so points back to Origin, which points back to the launcher, at least under normal circumstances. This I know is how things work because many players have tried it and reported the results over the years.
