The sims 3:Into The future(really hope Im posting this in the right section)

Hi there,

Im having an issue with my download. So in my current sims game, I have The Sims 3:Season, which works perfectly great. Today I decided that I want to download The Sims 3:Into the future. The download worked well, I got it installed on my computer but when I went into the #crack folder and tried to drag the documents in it into C:\Program Files (x86)\Electronic Arts\The Sims 3\Game\Bin  (as the instalation guide says) it pop'd a message saying that there is already a file with the same name. So I'm not exactly sure what to do. Whether to replace it, or move it and keep both... It'd be a great help if someone could tell me, because I don't want to mess it up.
Thank you!

Update edit: So I decided to move the existing (TS3W and TSLHost.dll) documents to a back up folder that I created(incase I needed it) and move the one from the #Crack. I went into my Sims launcher and I saw that it is there (at the bottom, you can see which add-ons you got installed) perfect. But A message pop'd to me AGAIN, saying I need to update my sims launcher, I decided to go ahead and do it but it isn't working for me. It's saying the above

And when I try to ignore the update the follow message pops

On a sidenote, never update your game via the launcher. Try the manual patch in cezra's guide instead. To update your game with the manual patch, simply run it.

Afterwards, apply the Ultimate Fix correctly as mentioned in the guide cezra's mentioned. Be sure to (re-)download the Ultimate Fix.

I got it to work. Thank you very much for your help
