help with error message/expansions/ stuff

i have installed the sims 3 and all the expansions and stuff pack from the websites.
--the sims 3 base game installation guide was correct and the game works correctly.

the expansions tell me to open the Sims3EP04Setup.exe and then i get an error message saying

>SetupNew\setup.cpp (140)
PAPP:
PVENDOR:
PGUID:
$15.0.0.498
@Windows Vista Service Pack 0 (7600)
IE Version: 8.0.7600.16385

then i have downloaded the fix.rar and i cant evan install these expansions to replace these files and when i do replace the files for the base game the launcher stops working!!

so i really need some advice on what to do please

Hello,

Please open the .rar file you downloaded using only WinRar, which can be downloaded from www.games4theworld.org . (If you use any other software than WinRar, like WinZip or 7-zip, the files will get messed up!)
When you've opened the file using WinRar, select áll the files in it and drag & drop them to a folder on your Desktop. When the extraction is done, close the .rar file and open the folder on your Desktop.
Now, start by reading the included "# Installation Guide.txt" and you should be able to get the game to work yourself. Good luck!

also what is the order i should install all of these expansions/stuffs?
