Run Sims 3 without Origin

sounds like your having same problem as me. Let me know what happens with your DxDiag on the errors and what operating system are you on windows . Post this info in the thread you started so that way I will save your specific thread that I can possibly use to reprot to EA

You should be able to sign into Origin in offline mode.

When did you buy the base game ? The newer base game version does require you to be logged in to Origin at all times but you can do so in offline mode. You do need to verify the installation once.

What error do you get when you try to login to Origin ?

Crin buguvy has another thread and he has same probelm with me with Origin. Origin has hijacked his game too.

It does depend on the version they have. You have two versions in Origin which may complicate things but if these people have the new version, Origin will start. That's how it works. Each case needs to be looked at individually and unless they state they have the old version and it doesn't work, it's all as it should be (not saying it's good, but that's how it works)

Crin op is having same problems as me. Origin has hijacked the TS3W file and the launcher as admin. It won't let him bypass the launcher and origin to play the game. When I click on properties on origin it states my computer is admin but what is happening is origin does not acknoledge ones own computer as admin and has taken over as admin.

Off line does no good because you need to be on line to get into origin to put it in off line mode. If the internet goes down or origin web goes down you cant play the game.

I never been able to play sims 3 without Origin, but I have no problem with playing offline, I put origin in offline mode and then I disconnect myself from the internet cause it's run smoother when I do. 

I have always been able to bypass Origin and the launcher and never had to get on line to play the game. The Launcher runs high disc usage and so does origin hogging your ram. Bypassing both the game plays even better. 

For me its still the same problem on the old version base game. I have both old and new and the probelm exists on both versions. I did a clean install with the oldversion and is what I have in my computer right now
