Another EP installation order question

I have the downloaded version of the base game, Late Night, Generations, Ambitions and High End Loft Stuff all installed and cracked and running (mostly) okay. However, I also have a retail copy of World Adventures that I have not installed yet. Can I install this just like I would normally (i.e. stick the CD in and let it do its thing), or do I need to do something special with it?

Also thank you all so much for this forum - it is so awesome and I really appreciate all that you provide for us simmers!

Hello,

You're welcome.
I don't know much about Mac OS, but for PC the instructions stay the same when you add an original copy to the torrented ones.
