The Sims 2 is an old program that causes/d issues for many, I thought I would share my experience of getting past "The Sims 2 Update Error" when installing expansions.
You will need this file, so download it now: http://www.mediafire.com/download/lzbxtj51r6b6e6r/TS2\_update.zip
- Install the Sims 2 normally from disc as an "Advanced User" to the directory of c:\Program Files\EA GAMES\The Sims 2
- Copy the files from inside the downloaded zip and folder to "c:\Program Files\EA GAMES\The Sims 2" and confirm to override the files already there. This will
- Install expansion packs in no particular order, making sure they are in "Program Files"!
- Enjoy playing the Sims 2!
Thanks, worked for me!
