Sims 3 installation problems

I have the The Sims 3 retail .I have downloaded the expansions from games4theworld a month ago without any problems but I removed them because I wanted to play the sims 2 again which is the complete collection by games4theworld.I'm trying to get the expansions again but i keep getting stuck at the installation.The installshield is asking for disk 1 everytime I'm trying to set it up.

It says please insert disk 1 that contains the file gamedata/contant_version.txt.
I see no disc 1 at all in the folder
So what I'm I doing wrong

It happens for every expansion I try to set up


Also my game version is 1.15.34

Hello,

Which Expansions are you trying to Install; the one(s) for The Sims 2 or The Sims 3 ?

The sims 3.I got it working now.Can we Install custom content?

Hello,

If you're using a retail version of The Sims 3 base Game, you can add original Custom Content. If your base Game is cracked, you'll have to Download cracked Custom Content. (Via torrents)
