@Gwenna1981 - I'm sorry, I thought you were asking if you had to uninstall everything in order to play the 64-bit version. And, like I said, you don't have to uninstall the LE version. Launch the game from Origin, with the advanced settings set to the 64-bit version, and it should not be an issue.
Did the game open the LE version even with your advanced settings pointing it to the 64-bit version? If so, are you starting the game from a shortcut? You may just need to make a new shortcut so it opens the correct version. Let me know if you need help with that.
I understand that the LE got installed for no reason. I've had Origin try to do that with mine as well. I *think* that Origin will install the LE version if you click "Upgrade", instead of "Update" for the patch. At least, that's been my experience with it. It's annoying, especially if you don't notice it and/or you're on a limited data plan. But having the LE version downloaded doesn't actually interfere with your ability to play the 64-bit game. Even if you open a save with the LE version, and it tells you it has removed items from the game because you don't have the packs installed, your saves should be safe as long as you quit without saving.
I hope I'm answering your question better. Please let me know if I've misunderstood, or if you have it set to 64-bit but it opened the 32-bit anyway
