you can but it would not be wise it takes up extra space and the games will be separate so i would recommend that you uninstall the sims 2 before installing double deluxe
Nightlife is all ready installed. If you can't find it, uninstall, then reinstall Double Deluxe. (I had a problem installing it, but nightlife was there).
Uninstall the Sims 2 you already have and then install Double Deluxe
If you have installed double deluxe already, you should just be able to install university.
You can use the Sims 2 Double Deluxe game CD.
Yes you can. Just Make sure that you have installed the sims 2 double deluxe first, then install Universty.
You need to have installed the sims 2, the sims 2 deluxe, or the sims 2 double deluxe, but not all of them. You just need to have the regular sims 2 installed to install and play it.
Yes you can
You shouldn;t need the Sims 2 Double Deluxe if you already have the Sims 2 installed, but you just do it the normal way, and when it asks you if you want to overwrite, just hit yes, everything will stay the same.
Yes! If you uninstall The Sims 2 PC and then re-install it your sims will be deleted!
Teens can only get pregnant if you have Inteen installed.
Your quistion was looking confusing but now it's not: You don't need all 4 to play the sims 2 pets; only one of them, so if you installed the sims 2 deluxe you don't need another 3 because it won't let you, because it has the sims 2 in it, happened to me when I had the sims 2 and the sims 2 deluxe: I had to uninstall everything just to get it on! You only need one of them, not all of them.
You just install the CD and it will come up as installed.
