Can I install EP/SPs from G4TW, even though I bought the base game/other EP/SPs?

Hi.

I was just wondering if there are any problems if I try to install Expansion Packs/Stuff Packs from Games4TheWorld if my Base Game (and a few other Expansion Packs) has been bought through Origin.  Thanks!

I have only used cracks but apparently it will work, if you install to Origin Games/ instead of Electronic Arts/ if that doesn't work try this https://games4theworld.forumotion.com/t1171-must-read-how-to-install-the-sims-3-correctly and using tips found here https://games4theworld.forumotion.com/t15229-sims-3-original-base-game-origin-pirated-expansion-packs

Yes, you can install non-original eps to original base game.
